We carried my 2017-stamped P-07 to the range and put about 300 rounds through it earlier this week. The pistol has >5K rounds through it. It has been detail stripped in the past to install CGW parts, clean and inspect, etc. but not for a couple of years and a couple of thousand rounds at this point. As usual it had zero malfunctions and accuracy was fine, including the last two magazines I dumped of some older carry ammo I had, standard pressure 147 gr HST's.
At home while cleaning it, I noticed that the front insert has developed a slight wiggle within the frame. In this pistol, as well as my other P-07, I have always found the front insert to be a tight fit with zero movement within the frame, even when I had the frame detail stripped to replace the trigger return spring. Now I can wiggle this insert very slightly... I can feel and hear its movement, and see a very slight movement in the insert and in the trigger. It seems as though the movement may be on a fulcrum of the frame pin that holds it in place.
So this is concerning me. With the frame assembled, I have inspected the insert, frame pin, and the frame itself, with a magnifying glass, to look for any damage or cracks and I don't see anything. I will detail strip the frame as necessary to get to the root of the problem. I actually have a spare front insert and frame pin, but I have never removed the inserts from the P-07 frame before.
I like to get input from other P-07 and P-09 owners here about their front inserts and any looseness or movement they may have noticed, as well as any experience with removing and replacing the front insert.
