I drop the slides on my CM9 and PM9 with the slide stop, I can do it any way I want with my CW9's... they don't seem to care. Like any 'short-action' pistol (think, even, a 3" or 4" 1911, etc... where the slide action is shorter than a standard model, and/or because of the low slide mass requires different recoil geometry...) the CM/PM's can be temperamental, that's probably one of the things holding me back from getting a Kahr 380.
Some of those guys have done a lot with those Kahrs... I'll have to trot back over and read about the follower mod. I've done some things... like making a CW45 mag from a standard 1911 mag, etc... but I don't recall seeing the follower mod... thanks!
Every firearm maker kicks out a lemon or two... Kahr is no exception. Their CS is pretty spotty, too... I did not have good luck with them and my faulty P45, and wound up trading it off for another CW9. I was actually standing there at the LGS, buying another CW9, once, and while the dealer was working up the paperwork, I was looking at the pistol. This particular pistol... the trigger had to be pulled back into the frame to get the darned thing to fire, like... crush it. I told him I wanted another pistol, which upset him because he had to do all the paperwork over. I'm sure he just put it back in stock... and eventually, someone else got it. I'm not a big fan of beta testing on customers, or making the customers be their QC department... so I feel your pain... but one pistol is not the entire lineup from a manufacturer. FWIW, some people did the same thing with Kimber... bad QC and CS... even though I've never had problem one with my 3 Kimbers. Conversely, I've had nothing but trouble with my Ruger revolvers.... sooooo, it's everywhere.
