Kahr PM40 and Pearce Grip Extension

Im having a problem getting my clip to fit with the Pearce Grip Extension installed.  Anyone else having this problem?  Should I just sand off a little of the extension?

thanks.

Mine fit without a problem; in fact, there's about 1/2mm wiggle room.

I  had troubles with mine too. When I FINALLY did get it installed the mag wouldn't always seat and lock completely in the pistol and would drop loose after a shot or 2. I messed with them for a long time and never did get them to work consistantly and eventually removed them.

+1.  

Mine went on easily, but I had the same magazine ejection problems (interestingly, also after 1-2 shots fired).  I also had a follower break while using the grip extensions; may have been a coincidence, but hasn't happened on two standard magazines.  I also went back to the standard floorplates.

As an aside, I was having very infrequent (but annoying) FTGB during long strings of shooting, which I attributed to fatigue-related limp-wristing.  I added a Hogue Handall Junior to the grip, which helped lock the gun in my hand and eliminated the FTGB.  I never had a problem with FTGB in the first 30-40 rounds, , and the Handall 'sticks' to clothing, so I take the Handall off for carry.
