I have many handguns, and this ones easy... my fullsize Beretta PX4 Storm in 9mm. I bought it back when they first came out (2004 I think) and it has literally never malfunctioned. I believe after the last range trip, it is nearing 3000 rounds of completely flawless perfection. I love the rotating barrel, it just eats up recoil. I recently bought the subcompact PX4 as well, and so far the first 500 rounds have been equally as flawless. I have a 45 on order that should be here Thursday. The PX4 is definitely my favorite handgun, and IMHO, one of the more underrated guns on the market. The gun shop had cases full of Glocks, XDs, and M&Ps... and 3 Storms. When I placed the order for the 45 version, the shop owner said "Yeah, these are awesome guns.... its too bad that sometimes the best products on the market aren't the ones people buy the most".
