I have a glock 34 gen 4 that I want to shoot for 3 gun and uspsa limited. If this topic has been brought up already I am sorry. So, I am not amazed by the stock trigger and there are so many options. Do I go with a oc custom, dk,zev, agency arms, taran, or something else? I really want a positive reset and as close to a crisp break as possible. Also, what else is recommended for a new limited shooter? I was thinking about Dawson sights and maybe grip tape. Also maybe a barrel, like a Wilson or a Kkm.
