Just picked up an MP9C, looking for a paddle holster, I have my shield for CC, so want this holster for IDPA and bowling pin matches, Amazon has them for full size, will this fit, the extra .25 won't matter for OWB.
For really tight and well made kydex or leather, the extra difference will wear on your holster. Not enough to do much damage, but the edges of the gun will shave off pieces of a well molded holster. There are several manufacturers that make 2.0c holsters. My new favorite is KT - Custom All Weather Holsters Practical Tactical.
I have a kydex Paddle Holster from barearms holsters. It’s pretty nice, but I’m anxiously awaiting my high ride snap leather holster from TT Gunleather. Kydex is fine, but I just prefer leather overall.
