This happened by accident, but while I am waiting to be able to get a holster for the P-10C, this was a happy accident.
While loading up for the range trip, I just on a whim tried the P-10C in a High Noon Close Encounter hybrid for the P-09. It locked in like it was made for it. The back is boned for a completely different gun, but it was just fine. Admittedly it as about half and inch too long for the shorter pistol, but go figure. Sorry for the real fast cell phone pics - my photos are usually higher quality than this.
So, I grabbed the High Noon Slide Guard for the P-09...not a chance, didn't fit whatsoever...weird.
