kiabe1 : The fault is not in our Glocks but in ourselves . I bet you are letting the Glock trigger induce flinch or trigger jerking . Try the drill in this video : https://www.youtube.com/watch?v=7KnBDIbgbMk
Glocks don't forgive human error. Keep it in a holster and get trained so your finger is straight along the frame unless firing .
Your last statement in itself shows Glock is not a good first gun. I see students having more problems with Glock then any other Gun.
1. Limp wristing causing FTF
2. Brass I'm face
3. Shooting low and to the left
4. Flinching and anticipating-light polymer
5. Trust issues with the trigger-Some treat the gun like they are walking on rice paper.
6. I also love it when I never see their Glock again-They have a new gun
7. These issues are fixable with a little extra one on one time, but I see the frustration/disappointment.
8. People start asks me if they can shoot my 226 instead
9. Glocks do not do so well in sales in Germany. There are way better guns.
10. I owned a G 17 in the early 80s, I traded it soon after. Was it for the Colt Mark IV model 80? I do it remember. No regrets even though paying extra on the trade.
To the OP, I hope the gun works out for you. Train hard on your skills and know your gun. Glock may be the right choice for you. Enjoy and good luck.
