Ok, I've decided to start shooting some local steel challenge and maybe IPSC. being a lefty, I decided to get a new gen 4 mod. 34 so I could swap the mag release. So far, so good. Well, after shooting a steel match last weekend, I think I want to replace/modify the trigger somewhat. I read, read, and read some more. Everyone says that their trigger group or spring setup is best. So, I want some feedback. What do you guys think? Is it worth the money to go all out and get a complete replacement or just swap springs and modify the housing with set screw for overtravel? Also, what brands are best and why?? Thx!
