Took my brand new G29 to the range and fired 158 rds. I had no FTF's or FTE's. The only problem I had was two misfires. On both rounds, there was a firing pin strike on the primers that would have been deep enough to set off the primer, except that it was centered halfway between the center of the primer and the edge of the primer pocket. In both cases, I re-chambered the rounds and they fired on the next firing pin strike. In reviewing the rest of the 156 fired cases, I found several that were also somewhat high off-center firing pin strikes, but they went on the first hit. Anyone know what might be causing this? It would appear that the slide and barrel are not locking up fully, or at least not consistently, so the firing pin is not aligned to the center of the primer. I also noticed some inconsistency with the elevation of POI, which may also have been caused by this.
