5 of 5 Extended / Ported .357 Sig Conversion Barrel April 20, 2026
Reviewer: Robert Miller from Shreveport, LA United States  
I ordered this conversion barrel for my new Shield 2.0 .40 S&W pistol. Just installed today, direct drop-in fit, no issues at all. I plan to visit the range later in the week to test it out, do not anticipate any problems whatsoever. I like the slightly extended barrel with porting, should help with the recoil of this cartridge. Thanks for making a great product!

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!

the rifling doesn't quite look even in depth at the end of the barrel. firing the gun is very reliable and seems accurate, as expected.

5 of 5 S&W shield 40/357sig conversion barrel October 3, 2024
Reviewer: Al Newman  
I purchased this as just a little project on my 40 shield. I bought the 4 inch ported 357 sig Conversion barrel. I must say just ran 100 rounds through her of target ammo and I'm more than pleased. Great fit everything worked as it should! So if you're looking for a little extra fun on your weekends, give it a try.
