OK I've had enough Kahr .40

Among other "things" I have a Kahr CW40 so called sriker fired, acts like DA only, some sort of damn poor plastic frame.

I've had a number of various jams / misfires, the latest being the recent outing with some other board members.

EVERY time I've pulled it apart to clean it, the (plastic) frame has generated "threads" that are being peeled off by the slide. Not sure the cause, you cannot get into those slide grooves to 'feel' or dress them very handily

Other intense dislike is there is VERY poor clearance to get the recoil guide pin back in You must install the barrel, the spring, the pin, and compress the pin and "hook" it in the front of the barrrel lug. Almost impossible to do. The construction of the barrel bushing does not permit enough angle and interferes with the sides of the recoil spring

Anybody, suggestions, good "sure fire" tune up tricks? etc?

ALTERNATIVELY, a similar "acting" weapon that is still compact, still DA only AND ALL METAL. I will concede to a light alloy frame
A Gunsmith friend of mine tells me that 95% of semi auto jamming prblems are related to the clip and lack of proper maintenence.
For this reason I do not carry a semi auto for my conceal carry.
