It's a very good barrel, but... - TRYBE Defense Smith & Wesson M&P 9mm 4.25in M2.0 Match Grade Threaded Pistol Barrel

The barrel is well made and it is perfect for compensator or suppressor use. The rounds seem to group as good if not better than the standard OEM barrel. I did have once issue. The barrel hood extension, where it fits into the slide, was .2mm too wide. It would not fit into the slide. There were no instructions regarding this, and I didn't know if it was an issue or normal. Their website says nothing, but other companies refer to it as a fitting by filling the sides down for fitment. A few minutes of filing got it to fit perfectly. When Customer Service finally got back to me, I was told I shouldn't have had to do that as they're supposed to fit perfectly bout of the box. My option was to return it for a replacement but these were on backorder for 3 months. So I went ahead and filed it and kept it. It was well worth getting and keeping but it took below grease to get it to fit perfectly. I would not recommend filing it if your not comfortable with carefully filing the sides of the barrel hood extension.
