I was shooting USPSA (rookie shooter) this past weekend with my 3rd Gen G17. It probably has 3k rounds through it and is stock except sights. I am shooting the same reloads as always and it was actually a little cooler than usual, so my W231 loads of 4.25gr with 124gr FMJ should have been more effective if anything. I also case gauge every round. I have only done the recommended manual maintenance and never a full takedown. Anyway, three different times mid-course of fire I had just a click with no primer fire. Under the gun for time, I just stripped the round off by racking and it went flying behind me, so I obviously can't comment on the primer strike. I texted an acquaintance of mine that took an armorers school and he said to look at the disconnect and trigger safety, since I replied 'yes' to his question of whether it was a 'mushy' click. I am not exactly what to look for, since it isn't a total failure. I was thinking maybe it would be a recoil spring issue maybe (not fully in battery?) or maybe a dirty striker. Anyone have this issue and resolve it? I haven't had any previous issues with this gun and am shooting the same reloads.
