5 of 5 .357 Sig February 2, 2023
Reviewer: Michael Pfeiler from Berea, OH United States  
I have put about 100 rounds through my new conversion barrel so far. The feed ramp is a little steeper than the one for the .40S&W so you do have to slingshot the first round home. After that though, no feeding issues. This barrel seems to be as high quality as the OEM Smith&Wesson .40S&W barrel. Only thing I would change is the incline of the feed ramp. Other than that, I love it so far. I look forward to trying some of your ported barrels for my shield40 performance center once they come back into stock.

5 of 5 M&P 40 to 357 Sig June 19, 2021
Reviewer: ROBERT SIMPSON from Newark, CA United States  
Just got the barrel, only took a week. Put a couple hundred rounds through it today. Very happy with this barrel. No issues at all with 3 types of ammo, shot more accurate the stock barrel. Looking forward to the 9mm conversion.

5 of 5 Excellent Service June 14, 2021
Reviewer: Anonymous Person  
Converts my M&P Shield 40 S&W to a Shield .357 Sig. I'm very pleased to have one pistol that has the ability switch rounds by simply changing the barrel.
Also, very pleased with the excellent service from TR enabling/Remsport. Fast service, fair pricing.
