Teamsterjohn Posted February 12, 2021 Share Posted February 12, 2021 I’m showing factory loads out of my 40 cal STI/ McCormick gun. What weight spring would be best for me. Thanks Link to comment Share on other sites More sharing options...

Gunsbygiz Posted October 19, 2022 Share Posted October 19, 2022 What about in a sight tracker setup with a lighter slide using 200gr federal syntec. I have tried 10-14 and can’t decide, but currently running the 11lb Link to comment Share on other sites More sharing options...
APL-G35 Posted November 10, 2022 Share Posted November 10, 2022 I always ran a 12lb in limited. Iron sight guns seem to just respond better to gripping the gun more so than any spring combo. Dot guns i feel get more out of spring changes, especially open. Link to comment Share on other sites More sharing options...
