I went to the range today and rented a Glock 21sf. I must say I absolutely loved the way it shot. The first thing I noticed is how soft shooting it was compared to other .45s I've shot in the past, which include the M&P .45. I kid you not, it felt almost like I was shooting 9mm. There was a little more of a push but that's it. Ammo was 100 rounds Indpendence 230 grain. Another thing is that, even though the grip was a little large for my hands, I shot it better than any pistol I've ever fired before, even after not shooting for 3-4 months. This is really weird because I've owned and shot other Glocks before. I was easily putting rounds in a hand size group at 10 yards, not to mention all the steel I knocked over in rapid fire. If I didn't already have a Sig Sauer P226 on order, I'd be buying a 21sf next week. I had no idea Glocks .45 ACP models handled this nicely.
