I already own two glocks: 21C and 23 both gen 3. I am looking to purchase a SC for carry because the 23 prints on me. I am a small guy and wear a t shirt almost every day. I am considering these 3: (gen 3 of course) G27, G29SF, G30SF. I know the 29 will be expensive to feed before I become efficient with it, that's not an issue. I cant find a 29 or 30 to rent or borrow. I have shot a 26 and it shot well. I am somewhat leaning towards the 27, just thought I would get some input from fellow glockers ? thanks Wanna kill these ads? We can help!
