Rented a G36 today, and had my 45 ammo from Buffalo & Corbon & Hornady. Holy smokes this little girl had some recoil action going on. Nothing I would notice in the 3 seconds it would take to empty the 7 rounds, but I was quite suprised, as my G29 with full power loads seemed quite a bit tamer. Anyway - I'm hooked, love the form factor, love the weight (or lack therof) I'll be getting one of them and a 33 and then my carry collection will be complete! Oh, a few FTE - the gun looked really dirty though so I'm not judging based on that.
