1.0 m&p trybe barrel - TRYBE Defense Smith & Wesson M&P 9mm 4in M2.0 Match Grade Non-Threaded Pistol Barrel

The TRYBE barrel was installed in my M&P 1.0 4-inch. The first 20 rounds were all over the place at 20 yards, which I attributed to a break-in period. Once the barrel settled in and properly mated to the slide, the grouping tightened up significantly. At 20 yards, I was able to achieve consistent 3-inch groups off-hand.

It certainly gives the Apex barrel a run for its money. Overall, installation was simple just dropped it in and it was ready to go.
