Picked up my new Kahr CM9 last night at the FFL holder's store. Non-firing check out was okay.
This morning disassembled it and did a semi-like-is-posted-elsewhere-on-this-forum cleaning a lube. Basically I ran patches through the barrel until they were clean, then ran one very lightly oiled (CLP) patch through it. I cleaned off the light, excess oil all over the pistol's internals, and followed up with some CLP. I forgot to clean the magazine. But It was dry and not dirty.
Disassembly of this CM9 is probably the most difficult of any of the 30+ handguns I've owned! But I did finally get it done. Reassembly was even more difficult for me! I followed the directions in the manual, which are actually decent, but it's harder to do than in looks on paper! I am sincerely hoping my next cleaning goes better. Everything was very tight and very unforgiving (i.e.,slide stop through the frame and recoil lug).
Shooting at the range started off not too bad. I did anticipate a more lengthy wear in than my S&W, Ruger, H&K and Sig pistols. I first loaded 6 rounds of Blazer Brass 115 FMJs, inserted the magazine with the slide back, did a slide-release (NOT slingshot). That chambered a round fine. I popped the magazine out, which was a little complicated. I found the easiest way to remove the mag was to use two hands - pistol in my strong hand, pushed and held the mag release with my weak hand until the mag feel out. (I suspect that parts will loosen up after 200 or so rounds and the mag will fall free with the typical strong hand thumb). Anyway, replaced the round just stripped off during chambering, re-inserted the magazine, did a slide stop release. Now I had a pistol loaded 6+1. Fired all rounds; did that three times. Each time the last round failed to lock open the slide.
Decided that Blazer ammo might be a little anemic, so I switched to Speer Lawman 124 TMJ rounds. Did a 6+1 reload as described about - fired that magazine and the slide DID lock open. Did another 7+1 mag as described above with the Blazer Brass 115 FMJ - the slide locked open. Short story: after about 30 rounds or so apparently the slide stop started working. However, when I again loaded a 6 round magazine with the Lawman ammo, I had a Failure to Feed; the bullet's tip appeared to catch on something just under the barrel's feed ramp. It did this maybe 30% of the slide releases with the Lawman bullet. I did not get this with the Blazer Brass 115 FMJ. I couldn't figure out why.
I then loaded several 7+1 magazine with one of my favorite practice rounds, Federal American Eagle 147 gr FMFP*s. These functioned without an problems. Of course, by then I'd fired 8 or 10 magazines of the Blazer and Lawman ammo.
Bullet Specifications, POI, and Notes - All Point of Air was center of target at 7 yards
Blazer Brass - 115 FMJ round is 1.153 in overall - POI about 5 inches low but centered - group size good.
Speer Lawman - 124 TMJ round is 1.147 in overall - POI about 4 inches low but centered - group size good.
Fed Am. Eagle - 148 FMFP round is 1.067 in overall - POI about 3.5 inches low but centered - group size very good.
*Full Metal Flat Point
Note: No difficulty with the short grip on this pistol. Works as well as my Glock 42. I do not feel I need grip extensions or grippier grips like Talon, etc.
After today's drill I don't plan on using any more Speer Lawman 124 gr TMJs in my Kahr CM9 until I've had a couple hundred rounds through it. Using it now would be just too frustrating. This is surprising, as I use that same round in many 9mm pistol and have had zero problems with it. I guess my CM9 just doesn't like it, at least at the initial introduction.
I DO plan on shooting up my large stash of Blazer Brass 115 FMJs in the Kahr. The Federal American Eagle FMFP works even better, but it costs me a bit more than the lighter bullet. I also have some Lawman 147 gr TMJ that I did not bring today; I will test that during my next range session.....I have a feeling it might not work too well if the bullet shape is like that on the Lawman 124 gr FMJ.
I am not going to even test carry ammo for another 300 rounds.
