The slide is easy to manipulate. Using the pinch-and-pull method or hand-over-the-slide method, the slide is effortless to rack, unlike some compact locked breech designs that require strength to manipulate the slide. The flutes in the chamber allow the pressure from a fired round to eject the empty brass cartridge.

The P7 does have an extractor, which helps makes the ejection run more smoothly, but in the case that the extractor breaks, you are not out of the gunfight.

The P7 will still run. Empties will still eject. The P7M8 I used for testing had a European-style magazine release in the butt. Later variants of the P7 used a thumb magazine release. The sights are large and easy to align.

Compared to other compact locked breech pistols, there was a difference in the cycling. Muzzle velocities varied among the cartridges, with the Liberty Ammunition screaming out the barrel at 1, fps.

The Hornady and Aguila were what you would expect, about 1, and 1, fps, respectively. I had a compact locked breech pistol along firing the same ammunition, and there was a difference in felt recoil. The P7 was softer. There were no issues with any of the ammo, and the P7 had a preference for the hot grain Liberty ammo.

My best five-shot group at 25 yards was 1. The P7 is not the lightest of compact pistols since it uses a metal frame, but that extra weight made the P7 a sweet-shooting pistol.

On average, five-shot groups ranged from 1. This old school pistol still has game. Field stripping the P7 is simple after removing the magazine. Press the takedown button, retract the slide and pull up. The slide assembly can then be slid off the barrel. Attached to the slide is the piston, which pivots on a pin.

When reassembling, the piston needs to be aligned with the cylinder in the receiver. The process is easy, albeit different from the takedown procedure of a locked breech pistol. The piston and cylinder need special attention when cleaning to ensure carbon and burnt propellant debris is removed. This is more complicated than the process for a locked breech pistol for sure. The P7 series spawned variants. Others included a P7M10 in. If a pal has one, ask to shoot it. It will be a lot less expensive than purchasing one.

If you do buy one, know that it will increase in value and that you will be eating Ramen noodles for a month. Editor's Note: This article is an excerpt from Gun Digest Log in to leave a comment.

Also, if losing possession of the firearm is imminent, the operator can render the firearm useless by removing the magazine. One disadvantage of the magazine disconnect is that it may add tension to components of the trigger mechanism, making the trigger pull uneven or heavy.

This is a danger because the user may dry fire the gun during or after the unloading process. When an empty magazine is inserted the firing system becomes reactivated, even though the trigger has been previously depressed.

The Sporting Arms and Ammunition Manufacturers' Institute stated that an "obvious concern with magazine disconnect features is that determining whether the gun is safe becomes linked to the presence of the magazine as opposed to actually checking the gun, opening the action, and making sure it is unloaded. Another concern is that if fatigue, debris or rust cause the disconnect mechanism to fail, it will most likely do so in the "fire" condition.

Further arguments are that functionally without a magazine the firearm is useless except as a club. Without the disconnect feature, a gun owner or police officer who accidentally releases the magazine in a gunfight would still be able to fire the bullet in the chamber; [15] if a magazine was lost or otherwise not available, then at least the gun could be chambered with a single round to be used as a single-shot firearm. A Pro variant of the Ruger LC9s was introduced in December , without a magazine disconnect, as a backup gun for law enforcement officers.

These safeties, similar to grip safeties, are de-activated as a natural consequence of the shooter firing the firearm, but are engaged in most other circumstances. The trigger is composed of two interdependent parts, and the shooter in firing the firearm manipulates both parts of the trigger. Conversely, unintentional pressure or a strike against the trigger is unlikely to do so, and such an action will not fire the firearm.

Such a design, made popular by Glock pistols but originally used in the Iver Johnson Second Model Safety Hammerless revolver , incorporates a trigger with a spring-loaded lever in its lower half. This lever which protrudes from the trigger face must be fully depressed in order to disengage a lock that allows the main trigger body to move. Unintentional pressure against the top of the trigger without pressing the lever does not disengage the lock and the trigger will not move.

Other designs include a spring-loaded pad that forms the upper portion of the trigger face and manipulates a similar lock. This design has more moving parts, but is advantageous in that accidental pressure on the lock release has reduced leverage thus requiring more force to pull the main trigger, where force against the lower portion does not release the lock and will not move the trigger.

The loaded chamber indicator is a device present on many semi-automatic slide handguns intended to alert an operator that there is a round in the chamber. It is a small button though sometimes a rod, such as on the Ruger series of. Such devices have been in existence for decades; [21] strictly speaking, loaded chamber indicators are not safeties, nor are they efficacious with an untrained user.

An indicator that is behind the ejector port does not rise enough to disrupt a shooter's sight picture , but enough to be easily seen or felt to alert a user that there is a round in the chamber to avoid negligent discharge of the gun. A trigger disconnector captures the hammer in the cocked position after a shot has been fired, even if the trigger is held to the rear as the gun cycles.

This ensures the gun can only fire in the semi-automatic mode, as the trigger needs to be released to 'reset' and have the disconnector release the hammer back to the trigger sear. It also prevents out-of-battery " slamfire " malfunctions that occur when a hammer follows the bolt carrier group forward as it closes. An alternative are striker-fired or " safe action " type firearms which have a consistent trigger pull requiring force greater than required by a single-action design, but lighter than needed for a double-action trigger.

Many such firearms do not have an external safety or external hammer Glock pistols and the Walther P99 and variants. In both cases, the action is very simple—a trigger pull always sends a discharge—and there are internal safeties to prevent non-trigger-pull discharge e.

Almost all modern semi-automatic handguns, except some exact replicas of antique models, have some form of safety mechanism including a "drop safety" that requires a trigger pull to discharge a cartridge. Single-action designs such as the Colt virtually always incorporate a manual safety, while traditional double-action pistols incorporate a decocker, manual safety, or both. However, the exact configuration depends on handgun type, year, make, and model.

Double-action only DAO pistols, which usually use designs similar to traditional double-action but without the ability to remain cocked, do not usually have external safeties.

Single-action revolvers have no external safeties, and they usually have no internal safeties, such as a hammer block or transfer bar, to render them drop-safe. Most single-action revolvers have a half-cock "safety" notch on the hammer, but many of these are not drop-proof. Real antiques are in this category; modern non-exact replicas may have internal hammer blocks. Carrying such firearms with a loaded chamber under the hammer, rather than with the hammer left down on an empty chamber, is not safe.

However, some single-action revolvers have relief cuts in between cylinder bores that allow the hammer to be rested directly upon the cylinder with no chance of interacting with loaded cartridges or primers. These are also known colloquially as "safety notches. Most double-action revolvers have no external safety devices; a sufficiently firm trigger pull will always result in firing. The heavy trigger pull required to cock and then fire the firearm usually prevents accidental discharges due to dropping or mishandling the gun.

Most modern double-action revolvers have an internal safety, either a hammer block or a transfer bar, that positively prevents firing without the trigger being pulled. The only double-action revolvers with external safeties are unusual cases available only on special order or modified through aftermarket conversions.

Pistols made and imported by Glock Ges. First, an integrated trigger latch prevents the trigger body from moving unless the trigger is positively squeezed. Second, the gun's striker-firing mechanism is locked in place by an extension bar linked to the trigger; the striker cannot move unless the trigger is depressed. Third, as with most pistols, a firing pin block actuated by the same extension bar prevents the pin coming into contact with the primer unless the trigger is pulled to clear the block.

Rifles come with various safeties. Some use a cross-bolt safety button, others a wing safety at the rear, or even a "half-cock" notch such as found on older lever-action rifles. The Winchester Model 94 originally utilized a "half-cock" notch safety but the design was revised in due to numerous inadvertent discharges. The M1 Garand created a safety with a metal rocking lever at the front of the trigger guard that is now called the Garand-style safety , used in the Ruger Mini rifle and Marlin Camp Carbine.

Some bolt action rifle safeties have three positions: "fire" which allows the gun to fire, "safe" which does not allow the gun to fire or the action to open, and an intermediate third position which cannot fire but allows the action to be opened to unload the rifle.

Common manual safeties for shotguns include button safeties located near or in front of the trigger guard and tang safeties located at the top rear or "tang" of the receiver. Button safeties are either left- or right-handed, but tang safeties are ambidextrous. From Wikipedia, the free encyclopedia.

It was revealed to the public for the first time in as the PSP Polizei-Selbstlade-Pistole —"police self-loading pistol". Prompted by the Munich Olympics Massacre , the German police decided to replace the. The pistol was also to be fully ambidextrous, safe to carry with a loaded chamber both holstered and concealed in a pocket , and able to be quickly drawn and instantly ready to fire.

Series production of the P7 started in The P7 is a semi-automatic blowback-operated firearm. This is accomplished by means of a piston contained inside a cylinder located under the barrel that opposes the rearward motion of the slide until the gas pressure has declined—after the bullet has left the barrel—hence allowing the slide to end its rearward motion, opening the breech and ejecting the empty cartridge case. The chamber has 18 flutes [6] that aid in the extraction process by allowing combustion gases to flow between the fired case and the chamber walls, preventing the case from "sticking" to the chamber walls.

The drawback of this system is that the breech "opens" slightly prematurely to allow the slide to initiate its rearward motion. The high temperature gases cycling through a tube located below the chamber area and above the trigger made the early versions of this pistol uncomfortable, according to some, to shoot after the content of two magazines were fired due to heating.

The advantages of this system are a simpler manufacturing process due to the absence of a locking system and a high mechanical accuracy due to the barrel being fixed in the frame; the barrel does not execute any sort of lateral or vertical movement during the operating cycle as with the Browning cam-action systems common to many other locked breech pistols. The P7's spring extractor is contained within the slide, while the fixed ejector is a surface on the slide catch.

The grip of this pistol features a built-in cocking lever located at the front of the grip. Before the pistol can be fired, this lever must be squeezed; thus this lever acts as a safety. The pistol is striker fired. Once fully depressed, only 2 pounds of force are required to keep the weapon cocked. If the lever is released, the weapon is immediately de-cocked and rendered safe.

This method of operation dispensed the need for a manual safety selector while providing safety for the user carrying the pistol with a chambered round, and increased the speed with which the pistol could be deployed and fired. The trigger and firing mechanism's method of operation and the unique slide catch were protected by U.

Patent 4,, , issued on January 2, The P7 is fed from a single-stack box magazine with a capacity of 8 rounds, [10] which is held inside the firearm's frame with a release located at the heel of the grip. After the last round has been fired, the slide will remain open thanks to a slide catch that can be released by pulling the slide further back or pressing the squeeze cocker. The pistol is completely ambidextrous and two-handed use is enhanced through the use of a profiled and enlarged trigger guard.

Between — the P7 received several modifications, mainly to address American market demand and shooter preferences. These modifications resulted in the P7M8 model. A new magazine release lever available on both sides of the frame was installed just beneath the trigger guard, which forced designers to modify both the pistol's frame and magazine. The firing pin and its bushing were also changed.

The pistols were marked with blue dots on both sides of the slide to differentiate the P7PT8 from other P7 pistols that can chamber lethal ammunition. The P7M8 is the P7's counterpart with larger trigger guard, lengthened trigger, heat shield, thumb operated magazine release, larger rear sight dovetail, protruding firing pin bushing and lanyard ring.

Production began in and continued until A final production run of P7M8 pistols were produced under the AH date code year Other than the slide marking no other features nor accessories were added to the usual kit. Only examples were ever made. Included in the package were a wooden lockable presentation case, P7 challenge coin, and special markings.

The slide's top-left radiused edge has the designer's name Helmut Weldle and "1 von " German, and including the double quotes; it translates to "1 of " in English etched onto its surface. The P7M13 is the P7's counterpart with a double-stack magazine and a round capacity.

A variant known as the P7M13SD was produced in limited numbers exclusively for German special forces, featuring a longer compared to the P7M13 threaded barrel and a sound suppressor.

The P7K3 is a shortened version of the P7 inspired by the HK4 pistol that uses straight blowback for operation. This version has a removable barrel and uses a sealed hydraulic recoil buffer in place of a gas cylinder. However, there are some commercial buffers available. When the. The slide of the.

The tool is needed to clean the inside of the floating chamber for safe operation. An additional exchange tool is provided for all calibers to screw and unscrew the barrel nut that attaches the barrel to the frame. Both tools can be seen in one of the pictures of the P7K3 on this page. P7K3's are more rare in the U. The P7M10 was introduced to the American market in However, it remained only a prototype due to excessive costs and complexity of creating such a weapon.
