also believe that it is a design flaw, which occurs in all (or most Kahrs), regardless of model or caliber. At least, I DO know that it occurs in the 4 different model Kahrs that I’ve checked!
It most likely goes unnoticed, unless you are using some of the more open mouthed, hollow points. However, if you slowly hand feed any round, you will notice the top several rounds will always nose dive (it seems to straighten out after a few rounds). In fact, if you fill the magazine, and look at the top round, you will notice a space/gap between the top round and the one below it (of course, the rear of the casing will be touching, but there will be a “gap” in the front). Then, if you use your thumb to move the top round forward (about a ¼ inch) it will close the gap, by taking a nose dive.
I only noticed this problem recently (after purchasing the cw40). However, I can tell you that the same thing happens in my P9, as well as my buddy’s pm9 and T9. I contacted Kahr and informed them of the problem (I even sent pictures ;-). So far they have ignored me.
One final bit of information. I have looked at more than two dozen other magazines (Taurus, S&W, CZ, Tanfoglio, Beretta, Glock, and several aftermarket types), and NONE of these magazines display that characteristic. Unfortunately, it looks as if owners will have to come up with a fix, without the help of Kahr!
