The stories I have heard about the Kahr's are not confidence inspiring.
I have two Kahr PM-9s. One I bought in 2002 or 2003 and one I bought in 2017. I think both had a bobble or two within the first few magazines, but they both work well. I found I can actually shoot better with the Kahr PM-9 than I can with my S&W shield. This is inexplicable since the Kahr has a longer heavier trigger.
For NPE environments or when wearing dress slacks or suites, I carry the PM-9 in a pocket holster. I have my some of my dress and suit pants tailored to have the pockets deepened a bit since most of them come with pockets that are too small for what I would normally carry--like my wallet and keys in my non-dominant side pocket. On my strong side pocket I only carry the Kahr in a pocket holster. I only carry it with the 6 round mag that does not protrude, because the extended 7 round mag makes it print and makes it more likely to get snagged if I try to draw it from the pocket.
