The 41 doesn’t really fit neatly into any competition I’m aware of. My philosophy is that you’ll also want to pick up another Glock besides the 19 to be married to if you get serious about any kind of competition. The 19 can definitely be used to win matches, but you don’t see top guys using them in any discipline. Might as well get used to the balance, timing, sight picture etc as early as possible.
A Glock 17 is PERFECT for GSSF and could still literally take you to Grand Master in USPSA.
A Glock 34 is PERFECT for USPSA, but can easily take you to Master in GSSF (you wouldn’t be alloweded to shoot AM Civ class, but could still compete and win Competition class).
Either would be greatly improved by a Vanek Trigger and Dawson Sights. A big competitive advantage would also be gained by shooting Atlanta Arms 124gr (or 147gr) Minor pf loads. Or better yet load your own.
Which do you prefer 17 or 34?
