Took my Dad to the range today to shoot my G21sf and new 92FS. My Dad brought along his Glock G20sf. Shot some 10mm Winchester Silvertips. That gun is a blast to shoot. I grouped tighter with the 10mm than I did with my G21 and 92FS which I shot before. It's kind of a sharp recoil, but not punishing at all. My Dad says the Silvertips have more pop than some American Eagle FMC that he found, but the Double Tap 180 Grain FMC had more recoil than the Silvertips. I can see why people enjoy the 10mm. It makes me want to trade by G22 for a G29 or G20.
