I recently picked up a .357 SIG barrel to use in my full size P320 40SW. Will I need to change the recoil spring/assy?? when using the new barrel?

Any help appreciated. THX

No. SIGs chambered for 357 SIG and 40 S&W have always used the same green paint recoil springs.

Thanks--just what I needed.
