My preferred GLOCK Gen is 3, preferred GLOCK size is a compact, preferred GLOCK finish the FPF, preferred GLOCK frame is the RTF2, preferred slide serrations is crescent. My choice for only 1 GLOCK (meeting all the above) would be a Gen 3 G23 RTF2 with crescent serrations along with a G32 OEM barrel, aftermarket 9mm conversion barrel and G19 mags to shoot 3 calibers. Very versatile with high collectibility factor and easily identifiable as different from most other GLOCKs.
Glock 23 with KKM 40-to-9 barrel and 9mm mags, G32 357 Sig barrel, (which I already have) And add to that an Advantage arms 22LR conversion barrel, slide, and magazines and Armscor 22 TCM 9r conversion slide and barrel
i think they're very well engineered pistols. i even like how they look. Very utilitarian. I don't like that my thumbs are too short to comfortably reach the mag releases.Just put my last for sale. maybe they'll make something in the future that I can use and enjoy. Maybe a 48mos with shield mags???
