One feature is the dual recoil spring system that spreads out the recoil force of the .45 ACP round by lowering the peak force of the recoil pulse. It also has 3-dot tritium night sights , a 5-inch national match barrel, ambidextrous safety, picatinny rail , and a desert tan Cerakote finish.
Reduction of perceived recoil discomfort is an immediate added benefit of this type of recoil buffer. [4] Some pneumatic recoil buffers used in firearms are fast, low-power gas springs. When compressed, they present initial resistance as the rod-to-seal grip is broken and then they move in a regular manner. An additional small spring can be ...
Free recoil / Frecoil is a vernacular term or jargon for recoil energy of a firearm not supported from behind. Free recoil denotes the translational kinetic energy ( E t ) imparted to the shooter of a small arm when discharged and is expressed in joules (J), or foot-pound force (ft·lb f ) for non-SI units of measure.
The action is automatically propped open after the firing of the last round in the magazine. The hammer, can be safely lowered by the decocking lever. Takedown is accomplished by removing the magazine, locking the slide open, and then turning down the takedown lever. The slide, barrel, and recoil spring will then slide forward off of the frame. [2]
Measuring the power factor is a quick and easy way to measure recoil, but has some drawbacks. While the power factor measures the momentum of the fired bullet, it doesn't take into consideration the firearm weight or the contribution from the ejected propellant gases which together makes up for the total recoil impulse from the firearm.
In firearms, a blowback system is generally defined as an operating system in which energy to operate the firearm's various mechanisms, and automate the loading of another cartridge, is derived from the inertia of the spent cartridge case being pushed out the rear of the chamber by rapidly expanding gases produced by a burning propellant, typically gunpowder.

Seventeen parts of the M1911 were reduced in size for the design of the EMP. The slide and frame were both shortened, necessitating changes to the extractor, firing pin, firing pin spring, and trigger bow, as well as the plunger tube. The grip frame circumference has also been reduced due to the magazine itself being made shorter, front-to-back ...
