I bought this barrel on sale and the price was exceptional. I only have about 80 rounds through it thus far so the review is very much premature. The only feeding issues came when using a specific brand of remanufactured ammo which I know to have a 3-6% failure rate so I do not fault the barrel, with factory new ammunition it has been 100%. With my reloads it has also been 100% (to the folks at Roscoe if I just voided my warranty there are no hard feelings on my part, I really don’t think I will need it).
Accuracy appears slightly better than what I get from factory 43/43x barrels. At 20 yards unsupported I can expect groups in the 3” range from factory barrels. This barrel I believe produced about 2 1/2” again unsupported so no complaints in that respect. I have not tried it from any sort of rest and I am not sure if I will unless I put an optic on the pistol I am using it with.
The biggest benefit in my opinion was what I got for the price. At roughly $80 this barrel is an outstanding bargain. I think if I had bought it at list price it would likely be a 4 star review but getting it for the sale made it an outstanding value. Based on my current experience thus far I would definitely recommend this barrel.
