Tempered enthusiasm April 21, 2018
Reviewer: Jack Rheiner from Edinburg, TX United States  
I received my S&W Shield .4o to 357 Sig conversion barrel. I was stoked and immediately dropped it into my Shield. It fit like a glove and is well made. However, when I loaded the magazine and attempted to rack a round, it failed to go into battery. The nose of the bullet nosedive on the feed ramp. The ramp is melonitited and not polished,  feeding was almost impossible. I took the barrel to my local gunsmith to have it polished. I believe this was solve the problem and it will be reliable. I will they came from the factory polished to save time. Otherwise, I am very pleased with the barrel and will have a powerhouse for an EDC.

Have to be honest! April 15, 2018
Reviewer: Scott from Valdese, NC United States  
I normally don’t write reviews but here is one. I bought this barrel wanting a small frame 357 sig. and that just what happened. The barrel went in my .40 shield perfect. The day I received it I went to the range. I shot speer lawman fmj range ammo which cycled perfect. I was very pleased. Then I finally found 2 types of personal defense rounds. I went to the range with them both a week later. I had hornady critical defense and Speer gold dot, both hollow points. I shot 2 clips of each and I had failure to feed almost every shot. I was pissed to the point I went home. After hitting the internet I bought a dremel tool and fine metal polish and polished the brown coating off the feed ramp. I have shot over 4 boxes of the hollow points since then, with out any jams what so ever. Just wish this would have came pre-polished. Soon as I get my new holster in, it will be my new edc. I love to shoot this gun now. BIG BLAST at 1350 ft per sec.
