Has anyone here used larger mags in their subcompact Glocks? I know the magazines are compatible and I was curious if anyone has tried it and has any feedback. I was looking at the magazine adapters online and the ones on Top Gun Supply seemed to be the best to me, but I'm a noob so I could be off (links: 22->27 23->27). I would probably still carry (when I get my CCW) with the standard 9-round mags but would like a bit more capacity for range shooting. Also, does anyone have any experience with Top Gun Supply? I know to stay away from that group of sites that's all owned by that massive company (tsgcom or something) but haven't read any feedback about this store.
