4 of 5 Needs a break in September 24, 2025
Reviewer: Joshua from Portland, OR United States  
Would not fully chamber HST's. Had to force the slide to lock. After about 5-6 rounds the slide went into full battery and hasn't had a pickup since. Ran 500 rounds of Underwood, Federal and Speer. Not a single hickup

5 of 5 .357 Sig Shield!!!! WOW! January 1, 2025
Reviewer: Danny Logsdon from Hyndman, PA United States  
Barrel arrived quickly, and we'll packaged with rust inhibitor.  Installed effortlessly, with perfect OEM fit.  I will definitely buy more barrels!  Wish you would make for SD40 4".  I would have one ordered today!
