My main beef with the Kahr's is all the work they require right off the bat to fucntion properly. I had to sand down mag followers to get my CM9 to feed correctly and rack the slide a good 500 times (LITERALLY--I used gloves ) to break it in. After that it worked great but it always left a sour taste in my mouth since I'm used to running Glocks and M&P's that have been rock solid from the first mag to 3-5,000 rounds and require no "fluff and buff".
