A&G Grip Extender

[sadsack67]

I have a Kahr PM 9; I have two of the A&G grip extenders; I put one on the 7-round mag. I was thinking about trimming down the other for the 6-round mag to make it lock into place. I would appreciate any views on this matter.
Thanks.

It's your gun. I can't see where it would hurt anything.
