I found and handled a G36 at a gun show earlier this year. Having been previously unable to make my former G21 and G30 bend to my will and be carried, I was on the prowl for another 45, but wasn't set on anything definate. The G36 felt pretty good in my hand, but I didn't go for it. Several months passed and I still looked. I saw a nice CPO SIG P220 and handled that as well.....more to my liking actually. I would have traded my G30 on the spot for that, but they weren't taking trades. I posted and add in the newspaper for my G30 and after several calls, came across someone who stated they might want to trade. Now I have a SIG P220 SAO! If Glock made a 45acp in the size of the G19 or G23...it would be my cup of tea. Since all of this happened, Glock has come out with the SF models in both the G21 and G30---they finally listened to the majority of their customers who prefer 45 auto. I haven't laid hands on either of those pistols as of yet, and carry my SIG when I can. Out of both my previous Glock 45's, I held on to the G30 the longest and tried my best...a bit top/forward heavy for me, but with a ten round mag capacity in a little jewel like that, I had to give it all the chances I could, but I'm now better off with the larger SIG auto and 8+1 in my book. Tjhing about the G36 is none of the pistol parts are interchangeable with other Glock models save maybe the trigger and firing pin? Mags don't seem to awful common for them at least around here although I've seen some at a couple different pawn shops locally. I've heard that the weight of the G36 pistol makes shooting the 45acp a bit more noticeable or more recoil sharp I guess....just what I hear. I love my G27 for the sub-compact carry and for right now, the 40 cal is my deep concealment, but I can hide the G19 just as well in the same IWB holster. I'd never want to talk you out of that G36, but I'd hope you got a chance to shoot one before comitting. Heck, you might like the G30sf. I'm still a Glock fan no matter what.
