I have an opportunity to purchase a new Glock 21. The only downside is that I have to trade my older G21 (a second generation I think) in to be able to afford it. My dealer is very excited about his, he stated that it shoots very well and recoils like a 9mm, possibly due to the finger grooves. Can anyone here tell me about their third generation G21? Does it really seem better than earlier versions? Thanks in advance.
