Edge40 Posted May 8, 2017 Share Posted May 8, 2017 (edited) Anybody know what the factory spring weight is. I put in a gray guns guide rod with a 15 lb spring and I think I want to go heavier. I like the feel the factory spring provides better than the 15lb set up. Thanks. Edited May 8, 2017 by Edge40 Link to comment Share on other sites More sharing options...
Sig0431 Posted May 9, 2017 Share Posted May 9, 2017 (edited) I have been told that 15lb 1911 spring is equal to the factory spring but I have personally not tested both to be for sure. I am running a 14lb in my P320 (9mm) for my reloads (135gr, 3.2 prima v). I am considering dropping to a 13lb. I have tried up to 16lb and so far prefer the 14.

BASE772 Posted May 9, 2017 Share Posted May 9, 2017 A Wolff or ISMI spring? In my experience there is a noticeable difference between Wolff and ISMI springs with the same rating. Link to comment Share on other sites More sharing options...
Sig0431 Posted May 9, 2017 Share Posted May 9, 2017 I have been using Wolff but for my next set I am going with ISMI. Link to comment Share on other sites More sharing options...

I shot them side by side with the exact same loads and there is definitely a difference. The 15 lb spring felt way snappier. Didn't like it nearly as much.

Sig0431 Posted May 10, 2017 Share Posted May 10, 2017 I thought the same about the 15# wolff spring, moving to the 14 was a big difference. Link to comment Share on other sites More sharing options...

I thought the 15 was snappier than the factory spring and was thinking it was because it was lighter. I didn't like how snappy it felt. Link to comment Share on other sites More sharing options...
Edge40 Posted May 26, 2017 Author Share Posted May 26, 2017 Nobody? That actually really surprises me considering the 320 interest on this forum lol. Link to comment Share on other sites More sharing options...
