Hi everyone i am new here and also new to open guns. My question is i am gonna be ready to take the leap in the next couple months for an open, But her lies my problem i wanna shoot factory rounds for the first year or so as i have an inventory already of 26,000 rnds. Ive done sum research and seen that sti offers the steel master thats will run factory just fine.Is their any other makers out their that offer an out of box gun that will run factory rounds without constant tinkering with it ?
