5 of 5 Easy drop in, nice quality machining August 20, 2025
Reviewer: Ed Underwood from Irving, TX United States  
Dropped it in my Shield 40, fit very well, better than stock 40 barrel. Fitted a comp to the treads and it functions very well.

5 of 5 Excellent Experience July 23, 2024
Reviewer: AN  
I have tried many conversion and “Custom/Semi Custom” barrels by most of the Major companies through the years. However; hands down the best experience has been with RemSport Mfg the Quality, Affordability and Customer service are Awesome.  Thank you!!!🇺🇸

4 of 5 Shield .40 S&W to .357 SIG conversion barrel July 10, 2023
Reviewer: James Cale from Chesterfield, VA United States  
Got the barrel.  Looks okay.  Haven't shot it yet.  High hopes as the previous 2 9MM 4" Shield barrels I've ordered did very well.

Hard to clean when you first get them.  Not sure why.  Hoppe's#9/patches/brushes don't clean it well.  Neither does carb. cleaner, nor Bore Tech Eliminator for lead or copper.  JB Bore Paste and lots of patches will get them clean/shiny inside.  Clean them before you shoot them.
