Other names for .380 ACP include 9mm Browning, 9mm Corto, 9mm Kurz, 9mm Short, and 9mm Browning Court (which is the C.I.P. designation). It should not be confused with .38 ACP. The .380 ACP does not strictly conform to cartridge naming conventions, named after the diameter of the bullet, as the actual bullet diameter of the .380 ACP is .355 inches.
.45 ACP Hydra-Shok, .45 ACP Hydra-Shok (reduced recoil), 9mm Hydra-Shok.22 LR HP, 9mm Hydra-Shok, 9mm FMJ. Hydra-Shok is a type of hollow-point projectile made by Federal Premium Ammunition. It was originally patented by ammunition designer Tom Burczynski.
A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters.

The Model CF-380 is a compact, single stack magazine, derivative of Hi-Point's 9×19mm handgun line. It consists of a polymer frame, zinc-alloy slide and bolt (with steel reinforcing inserts, and a steel breech, chamber and barrel. Its low price and small and compact design prompted many to purchase it for concealed carry.
The short recoil action dominates the world of centerfire semi-automatic pistols, being found in nearly all weapons chambered for high-pressure pistol cartridges of 9×19mm Parabellum and larger, while low-pressure pistol cartridges of .380 ACP and smaller generally use the blowback method of operation. Short recoil operation differs from long ...
The Walther PK380 is chambered for the .380 Auto (9×17mm) cartridge, and its design is very similar to the .22 LR (5.6 mm) Walther P22, which in turn is based on the larger Walther P99. Like the P22, the PK380 features a slide-mounted, ambidextrous manual hammer-block, non-decocking safety and an external hammer.
Rather than inert bullets, Gyrojets fire small rockets called Microjets which have little recoil and do not require a heavy barrel or chamber to resist the pressure of the combustion gases. Velocity on leaving the tube was very low, but increased to around 1,250 feet per second (380 m/s) at 30 feet (9.1 m).
In both the open and standard rifle divisions, minor power factor is dominating due to less recoil, and 5.56×45mm/ .223 Rem is a common caliber. Ammunition loaded to major power factor such as 7.62×51 mm/ .308 Win has a bigger recoil impulse, and is regarded as having an advantage on stages with targets at long range.
