The .40 S&W (10.2×22mm) is a rimless pistol cartridge developed jointly by American firearms manufacturers Smith & Wesson and Winchester in 1990. [3] The .40 S&W was developed as a law enforcement cartridge designed to duplicate performance of the Federal Bureau of Investigation's (FBI) reduced-velocity 10mm Auto cartridge which could be retrofitted into medium-frame (9 mm size) semi ...
This became known as the "10mm Lite", or "10mm FBI" load, or attenuated 10mm, remaining common from various manufacturers today. With some pistol reliability problems increasing in this lighter load, [ 18 ] Smith & Wesson observed that a version of the 10mm case reduced to 22 millimeters in length from the original 25 mm could be made with the ...
Ed Sanow also felt recoil was equivalent to 230 gr (15 g) hardball in .45 ACP. [6] In addition, the bottleneck case can function better than a straight case with a wider variety of bullet shapes and sizes and allows the use of fully supported barrels. [3] Ballistics fall somewhere between the .40 S&W and the 10 mm Auto. [7]
This edition is a special dual caliber offering of the Combat Elite semi-automatic pistol. The pistol is furnished in .40 S&W and includes a 10mm Auto conversion kit consisting of a barrel slide stop, two recoil springs and guide, and a stainless steel 10mm magazine. In addition, each pistol is specially roll-marked "ELITE TEN/FORTY" on the ...
The .40 will have less recoil because velocity is significantly lower. In fact the Wikipedia article on Recoil gives a direct comparison between the 9mm parabellum, the .357 SIG and the .40 S&W. Recoil with the .357 SIG was roughly twice that with the 9mm, and roughly 50% more than the .40 S&W. The article also explains that since acceleration ...
This can be a problem for magnum revolvers or rifles which simultaneously chamber more than one round of ammunition, as the recoil from the firing successive rounds can loosen the bullets in the remaining cartridges, and cause their bullet seating depth to change, which can have a serious effect on accuracy, or could, in the case of a revolver ...
In 2010, S&W introduced the SDVE model, nearly identical to the SWVE, however with some major improvements. The SWVE was redesigned to be more similar to the Smith & Wesson M&P , with improved ergonomics, a redesigned extractor, wider slide serrations on both the front and back of the slide, a Picatinny accessory rail and an improved trigger ...
The 10mm Auto is a rimless automatic pistol cartridge, so moon clips are used to hold cartridges when loading and extracting spent cases en bloc. The Model 610 can also chamber and fire .40 S&W rounds, as the .40 S&W cartridge is a shorter, less powerful variant of the 10mm Auto with the same diameter.
