Finally got some time over the holidays to get to the range with my new G21SF .45. Put about 200 rounds through it so far and its nice!! As a point of reference i have a G17 also (1995 model), shooting both back to back i was very accurate with either, will the .G21sf has more kick to it, its not instrusive at all, however, rapid shooting takes a firmer grip than the G17. I find this interesting, i have 3 shooting ranges in my area, and their policies are widely different. Range A requires you to purchase a 7 day pass watch a 30 minute video and you have to purchase you ammo from them. Range B has to inspect your pistol(s) and if you have ammo loaded you cannot shoot that day. Range C does no checks or inspections, basically shoot what you brought.
