I have a Beretta PX4 Sub Compact I carry when I'm not carrying my 40c and was concerned with 147 grain JHP bullets expanding properly under the lower velocity from a 3 inch barrel verses a full size weapon with a 4-5 inch barrel producing a much higher barrel velocity ..

Testing with what was available - water filled gallon milk jugs with 4 layers of denim from a pair of jeans !! All of the different brands of JHP in 147 grain I tested expanded shooting through this configuration .. some did expand slightly more then others but all the modern rounds expanded in the 3 inch barrel..

The one that I thought expanded the best was Western Defend and that is the one I carry after my experiment and watching video of test of the round being shot into gelatin that is on YouTube ..

A series of video's called Ammo Quest on YouTube tests many of the most popular bullet sizes and weights in a controlled environment that comes close to simulating FBI Testing Controls ..
