I have a Glock 20C.
It was purchased for use in bowling pin matches.
Works well with warmish hand loads.
If I was to do it again, I would not buy the C model.
I do not mind the ports, but I do not feel the ports
provide any real benefit for my application.
If it were for a carry gun,
I would definitely NOT buy the ported model.
I own several 10mm pistols in various platforms,
but I prefer the S&W 610 revolver.
Reloading can make owning a 10mm more affordable.
The Glock is a good platform for 10mm.
I enjoy shooting mine.
Which reminds me,
I should take it out to the range next time.
Glocktoys has my old G20 now, great weapon!! He installed an efk firedragon recoil assembly and it really tamed the recoil big time, but still feeds light reloads and fbi lites just fine!
