After having two of the locked back stoppages in the first 15rds of 50rds, I was able to make it back to the range. Note that I didn't clean or oil the pistol. I shot 25rds of Speer 124gr TMJ Cleanfire, 25rds of American Eagle 124gr TMJ NT, 50rds of Speer 147gr TMJ Cleanfire and 64rds of Federal HST 124gr JHP's. The pistol functioned 100%. Accuracy was below par at first, but did improve over time. I don't know if the accuracy improvement was due to the pistol getting better or me getting better with it. If this pistol will work through one more trip to the range, I'll forget about the two stoppages in the first 15rds.
