Huumm. Armor piercing too !!! For get the standard pistol cartidges. For get stainless steel. Carbon steel firearms have worked well for a long time , back in the match lock flint lock days. Not many pistol cartidges are armor piercing. Think about a 5.7x28 FN in the five-seven pistol and carbine and the 4.6x30 HK maybe . IF you capable of owning them over there. Otherwise Buy what you can service over there like glock, hk, sig in a cartridge you can buy loads of ammo for.
One shoot kill ?? Practice , put a ..22lr or 22mag on the center of there face and there died or scambled. Heck ,Buy a AK47 or 74 in a carbine and pistol .
Might as well have one of these also . Killed a lot critters and been used on people too . Easy to buy and carry 5000 rounds if needed. Get good with it.
