Bought a glock 20 a year or so ago... mostly for power. Great shooter, and there is plenty of power. Bought a storm lake barrel for it and turns out it's an even better shooter. Don't look past the 10mm it is a great gun! I use this as my hunting sidearm and have finished a few animals with it, and it did its job well! I have never had a malfunction with the storm lake barrel after about 1400 rounds through it.
