I have three magazines total for the weapon. During early function testing I identified an ejection problem that only occurred with one of the magazines, and even then, only on the last round. I have never bothered replacing the magazine or trying to identify what causes the malfunction. Instead, I simply marked the magazine and make sure that, when I’m carrying both spare magazines, that marked one is my LAST magazine used. I figure, if I’ve fired my last round, then does it matter if the extracted brass doesn’t clear the ejection port? I’ve got no more rounds to fire at that point anyway so there’d be no need to clear the jam.
On the range the weapon still performs well. With its 3.64” barrel, even from 25 yards, I’ve never had a problem keeping all the rounds well inside the 8-ring on a B27 target. Usually they’re all within, or darn close to, the 9-ring. When I’m shooting for speed instead of accuracy (a happy balance we all seek) I can still keep the shots inside the 8-ring with no issues.
Across the 5K+ rounds I’ve fired, I’ve shot every type of ammo except Blazer and Wolf. I’ve shot ammo from every other major manufacturer of .45ACP ammo. I’ve shot semi-jacketed hollow point ammo, full metal jacket ammo, semi-jacketed soft point, etc. The only malfunction I’ve experienced on the range is that cited above: the failure to eject the spent brass from the last round in that one magazine.
As a final footnote, I’ve recently accepted a challenge from a friend of mine to build and test a survival vest on a three day two night weekend outing. All I’m allowed to take with me is what I can carry in or on the vest and my pants pockets. The Kahr CW4543 will be my “survival” weapon for that weekend, obviously not meant for hunting but purely carried for defensive purposes. After I’ve survived that weekend, I’ll give you all an update on how that goes.
