Ok. I have just purchased a .25acp Beretta Jetfire and I was hugely disappointed after I have read this thread yesterday. To the point that I started thinking of shelving this beauty of a pistol. Than me and a buddy of mine decided to test it for ourselves to be sure. You see, after reading about the .25 acp bulllets "being stopped by heavy jackets" and "having bounced off trees and hitting the shooter in the leg" and "getting stuck in the skin so that one could remove them with fingernails" we kind of felt bad of our Berettas. Ok. We have taken 3 catalogues totaling almost 3 inches in thickness. In order to make sure that we do account for the infamous "heavy jacket .25 acp bullet stopping power", we wrapped the catalogues in 2 layers of heavy canvas. Than, we shot the package with a 50gr Fiocchi FMJ and a 35gr Hornady HP. The FMJ went through the package and we never recovered it. The HP went half way through and got stuck in the middle of the second catalogue in the bundle with insignificant resulting expansion and impact cavity with cracks going well into the third catalogue. I can honestly say that even though I agree that .25acp is not an ideal primary weapon choice by any means, I respect the round and I would hate being shot with it. Also, I do not believe in bouncing bullets and bullet stopping jackets after what I have seen. I have the pictures if someone interested. And, yes, I do like my tiny Beretta and will keep caring it as a back-up with no second thoughts. FMJ is the way to go though.
