True Precision Sig Sauer P365 XL X-Macro Recoil Spring Tuning Kit

Five springs, one guide rod, and a way to tune a P365 XL or X-Macro to whatever you are feeding it. The kit runs 12, 14, 16, 18 and 20 pound chrome silicon springs, which covers light target loads on one end and a compensated or suppressed setup that needs a heavier spring to stay in time on the other.

The stainless guide rod is a non captured design and comes with its screw and bushing, so changing spring weight takes a field strip and about a minute. Both 3.7 inch slide models take the same kit, so a P365 XL and an X-Macro in the same safe can share one box of springs.
