I have had both the MK9 and the PM9 for a while now. Kahr says to allow for a 200 round break in period. I have fired 600-800 rounds through each of the guns with one FTE from the first mag with each of them...AND NO other issues since.
The smooth front and back strap on the MK9 can be a problem if your hands are sweaty but the (some say agressive) stipling on the PM9's grip make it easy to handle. (No blistering or soreness after as many as 200 rounds at a time)
They are both as accurate as you are within 15 yards, which for SD purposes is as much as you can ask for.
I like them both and will carry either every day depending on how I'm carrying that day. - B. B.
I give this pistol high marks. I am a fan of the 1911 45 ACP, and yet am always looking for a light conceal carry weapon in a minimum of 40 cal. This fits the bill. I have found the gun to be reliable and I can shoot it well. Keep looking for one lighter! I've not had jamming problems. I think many problems with well designed autos jamming is the ammo. - J. M.
Good choice, but violent to shoot in 40S&W. Own several of the larger frame, in 40S&W, and they are fantastic. Used one for CHL and had no problem even at longer range. The smaller gun is perfect for lady's purse or pocket. They seem less troubled by the smaller item.
The extended grip magazine from Kahr ( for their short handle or smaller frames ) will not work correctly. I do not fault them, as this is a difficult item and the price is still quite low.
I shall try to get this corrected by a local gunsmith, or perhaps just try to add a small dot of solder sufficient to move the magazine either forward or rearward ( in the manner of a 'shim' ) on the exterior front or rear surface, in order to effect a cure. Second, or follow up round will not feed from extended magazine. Of course, the average encounter, as per statistics, does not involve but some 2-3 rounds. - L. H.
