Back to the range today with the Covert R9. Fired Lawman 115, Spear Gold Dot 124 and one mag of Spear Gold Dot 147. Absolutely no problems until the last 2 6 shot mags when the trigger wouldn't predictably reset after the shot...grips were loose (tightened yesterday after shooting, loosened up after no more than 40 rounds fired!). I had Loctite blue on them a month ago, but apparently not enough. Going to get some of John's grip screws for sure!
Still a little worried about the movement of the firing pin retainer locking back the slide...would suggest anyone with that problem in the future do the following:
1. Let the pistol cool off
2. Pull the slide back as far as possible and let it go as if loading a first round...this may or may not work...
3. If not, slap the right side of the slide just above the grip sharply several times (preferable with the slide held as far back as possible which may require another set of hands to help) and retry #2...
4. If that doesn't work, pad the right side of the slide and tap sharply with a rubber mallet and repeat #2.
From the pictures I posted, it would appear that the retainer slips or rotates to the left (non-ejection) side of the pistol, and getting it to go back to the right will allow the slide to release. The question now is why does the retainer move, and should the pistol go back to the factory before being a CCW.
