Please explain.
The 9mm Kahrs are the best of the bunch, and are not affected with any of the rare issues that have been known to affect some of the .40 or .45 models. Buy with confidence.
Honestly, I would argue about those issues being "rare", as BOTH my CW40, and my PM40 suffered from the same issue of unwanted magazine drops EVERY shot, and you'll find a huge number of horror stories on the web for those models as compared with their competitors,...but anyways...
"best in the bunch, and are not affected...."
I disagree based on my experiences with Kahr polymer pistols. I have had various problems with every single one of mine including my PM9 that have caused me to dismiss them from my CCW options for reliability issues. Most of my problems with the PM9 have had to do with feeding issues and an overly tight chamber, but I can also list the slide stop spring as a design SNAFU that, if you research online, causes many people grief....not the least of which is Kahr, because of the returned guns and requested spring replacements.
I believe my PM9 has the same polymer magazine release that caused constant malfunctions with my PM40, a feature that Kahr redesigned with a metal replacement in later guns because of the overwhelming number of failures experienced.

Like I said, many people think they are great pistols, and many people live trouble free with them, but many people also have problems with them, and don't think much of the design and inherent flaws/weaknesses that were designed into it. I myself am firmly in the latter circle,and am the owner of a PM9, a PM40, and a CW40. I loved them, until I didn't.
I do know they have had several design changes that have directly addressed issues that Kahr has had with their polymer pistols.
