There’s more to a bullet than just a ball of lead and smokeless powder. In this article, we’re going to go over a bunch of different pistol calibers and then discuss some interesting ammunition options available in them. There are a lot of different proprietary ammunition types (Hydro Shok, etc.) and while they are indisputably awesome – we’re going to stick the major variants.
Micro Ammunition Classes
There is obviously a lot more smaller ammunition classes but these following examples are definitely common for micro and sub-compact pistols for concealed carriers.
- .22 LR
Small, lightweight, and extremely affordable – this is often the first ammunition a shooter will ever use. Recoil is negligible. This allows the shooter to acclimate to the fundamentals of firearm safety. Is it still lethal? Yes. In fact, .22 LR is a preferred ammunition style for those on long range expeditions who may need to either defend themselves from animals or eat them. So don’t let it’s small size fool you – it’s capable.
- .25 auto
This one isn’t nearly as common as it used to be. The .25 auto round was thought to be the perfect middle man between the .32 auto used in some European police pistols and the .22 round used for recreation. Recoil is, again, minimal and it affords more rounds into a limited space than a .380 auto.
- .32 auto
James Bond’s classic Post WWII Walther PPK was chambered in .32 ACP. Perfect for British spies, old European police pistols, and concealed carriers – pistols chambered in .32 auto tend to fit easily in the palm of smaller hands.
- .380 ACP
There has been quite some debate as to whether the .380 auto has the penetration power necessary to compete with a 9x19mm round. It was engineered specifically to fulfill that purpose for micro and sub compact sized pistols. The big difference between it and a 9x19mm round is 2mm in length. So, .380 ACP could really be called 9x17mm.
