http://www.px4storm.com/ I got to put 50 rounds through on at the range. Most comfortable gun I've ever fired. With the large backstrap it was perfect. Felt better than the Walther p99 I've been looking at, but haven't fired, I think that was due to the slightly longer grip so it doesn't cramp my thumb. It was only 50 rounds but I didn't experiance a single problem with the gun.
