True Precision SIG P365XL/XMacro 3.7 in Recoil Kit

The True Precision SIG P365XL/XMacro 3.7 in Recoil Kit is a recoil-spring tuning kit for 3.7 in SIG P365XL and XMacro configurations. The 3.7 in designation is an important fit detail because P365-family recoil systems vary with slide and barrel length. The black kit is identified for the 3.7 in SIG P365XL/XMacro configuration, making slide and barrel length part of the fit check.

A 3.7 in P365XL/XMacro should be evaluated with its complete slide and muzzle setup because even small configuration changes can influence recoil-spring behavior. On a 3.7 in P365XL/XMacro, recoil-spring changes can influence slide speed and battery return, so tuning should account for the complete upper assembly.

Verify reliable cycling, extraction, feeding, and slide lock with the intended ammunition after any spring change is made. During P365XL/XMacro testing, watch for incomplete cycling, sluggish battery return, or abnormal drag that could signal a poor spring match. If the 3.7 in SIG setup cannot be made reliably functional, have a qualified gunsmith inspect the recoil system before more live-fire testing.
