Really like the finish everything went good until I was putting the parts in the frame. After several attempts to put the trigger housing, the metal sleave and pin into the frame everything didn't line up. I kept thinking it was the trigger housing or the frame holes were not right but it turned out to be the metal sleave that sits on either side of the trigger housing which in turn is slid into the frame. The holes in the metal sleave weren't even close to lining up. Prior to doing any metal work I decided to try one of the sleaves from the other two P80 frames I had completed. I was able to mix and match to the point that I had all 3 together without doing anymore drilling/grinding. All three seem to function ok but have not been to the range yet to do a live fire test due to the -minus degrees here. I'm hoping everything works and that I haven't messed up the reliability of the other two frames, which were running perfect.
