In the continuing quest for powerful, small, lightweight CCW I've accumulated MK40, P40 and PM40. Last year got the CW9 for cheaper trigger time as ammo costs continue to rise. The CW9 and PM40 had issues out of the box. Kahr sent me the replacement mag catch for the PM40 in record time in response to my Email enquiry. The CW9 had to go back, turn-around could have been faster but the blame is at least 50% my dealer for being slow to ship it and forgetting to call me when it came in
The CW9 has been perfect since, shooting mostly the cheap Monarch steel cased ammo.
The CW series is a good buy IMHO, basically the same as the P series but with standard rifling instead of polygonal so you can shoot cheaper lead reloads at the price of a bit of velocity loss with factory ammo compared to the polygonal. They also lack the dovetail front sight so are not a good choice if you want night sights.
I'd rate them execellent except for the fact that many have problems during the first couple of hundred rounds. The repaired CW9 is holding up well as I generally shoot a box of ammo thru it every range trip.
Spare mags for the Kahr are way over priced and the CW series only comes with one mag, the MK/P/PM series come with two. But the new Pro-Mag aftermarket Kahr magazines have worked well in my CW9 and are less than half the cost of the factory mags. They come in 7 and 8 round versions, and both have worked great in my gun. I've not had satisfaction with Pro-Mags very often, but am happy with these.
In this power, size, weight combination your choices for something else are nil in .40 and pretty much the Kel-Tec P11 or PF-9 in 9mm (or Rorhbaugh is money is no object) everything else is significantly heavier and probably larger as well unless you drop down to .380ACP.
