I apologize f this has been answered elsewhere; I did a search and
was unable to find anything.

My CW9 (bought used a couple of months ago) has a finicky mag release.
Doesn't seem to make any difference full/empty, - two different Kahr 7-rd.
Release button is hard to depress & subsequent release is hit & miss.

'Don't believe it's dirty or lube issue. What should I look for?
