I bought one of the first to come out Kahr PM40 pistols and did a side by side comparison with my Glock 27.
Smaller and lighter than the Glock 27, easier to carry in the front pocket in a pocket holster, more accurate and believe it or not I thought felt recoil was less. However I would recommend the Glock 27 to everyone and I would not recommend the Kahr PM40 to anyone.
I put 1500 rounds of various 40 caliber ammo through it, Sportsman's Warehouse sent it back to Kahr THREE TIMES and it still does not work. Never charged me a dime and excellent customer service from Sportsmans Warehouse I highly recommend them for good prices on new guns. Excellent customer service from Kahr but when I hear about how excellent customer service is from a gun company I always think that just indicates problems with their guns. MOSTLY FAILURE TO RETURN TO BATTERY ALMOST EVERY MAGAZINE, ALSO FAILURE TO FEED, FAILURE TO EJECT, THE MAGAZINES FELL APART, THE PLASTIC FOLLOWERS BROKE OR THE BACK OF THE METAL MAGAZINE TORE OUT, ONE MAGAZINE WOULD ONLY HOLD ONE ROUND LESS THAN THE OTHERS SO I TOOK IT APART THEY HAD INSTALLED TWO MAGAZINE FOLLOWERS IN THE MAGAZINE ONE ON TOP OF THE OTHER. IT SEEMS LIKE KAHR IS A HIT AND MISS PROPOSITION I WOULD NOT RECOMMEND THEM ALTHOUGH SOME PEOPLE SEEM TO HAVE NO PROBLEMS AT ALL.
