When I researched a replacement for the first gen LCP I was looking at anything in the category which fit requirements. There is really no way to know if any one gun model will be "reliable." It's the gun you get that you have to deal with. In reading the posts on Kahrs I came across two issues with them that seemed to be consistent complaints, first, that many were new to firearms, and second, they brought a "consumer" attitude with them that demanded a lot of hand holding. When disappointed about something the firearm failed to do, a lot of times it was based on expectations - one issue was that they intended to shoot anything they wanted thru it, regardless of the fact that a lot of Kahr's design philosophy is oriented to self defense and the use of full power rounds.
One thing that self loading guns of any stripe require is good ammo - this issue has existed since they were invented, and low power fodder getting into them was even a problem in the early 1900's. Ammo makers weren't loading rounds to meet the requirements of cycling the slides even then, and there continues to be issues with self loaders to this day when owners choose ammo based on price, not performance.
Another issue was the requirement that Kahr states up front - shoot 200 rounds thru the gun before contacting them about feeding and extracting issues. They get a lot of internet hate for something that most professionals consider to be inadequate - they won't trust any gun for self defense with less than 500 rounds thru them. Goes to the consumer vs experienced gun owner and we've had our share of threads here on it.
Then we get to loading the gun properly - one highly popular make asks you slingshot the slide to load it, Kahr states you rack the slide, use the slide hold open, insert the mag, then drop the slide release and let the slide load the round into the chamber. Using the other gun's method only increases the chance of riding the slide and that is the #1 method of creating a chamber misfeed in any self loading action. Nonetheless internet "experts" tell you to ignore the specific instructions in the Kahr owners guide. When they do they complain about problems.
There is also the complaint about "heavy" Kahr triggers - which are 6 pounds. So is the trigger on most field use and tactical guns, not 2 pounds. 2 pounds are target triggers meant for stationary use on stationary targets. The public thinks that if it's a "better" trigger for range use, it will also be "better" for field use - and when doing so, the rate of ND's and the consequences go up. The problem is putting race gun tech into a field and EDC gun. When you modify the working envelope of performance and force it into a narrow focus you then are moving it's optimal performance away from one area to gain in another. Case in point - cars - hot rodding them for better drag strip performance eventually results in a cantankerous, abysmal demon which gives nothing but trouble trying to get to the store for a gallon of milk and loaf of bread. I would no more tolerate preheating the engine, priming it with ether, jumping thru the roll cage to start it, and then trying to drive on slicks in a pouring rain with no windows, than you should carrying a 2 pound trigger, target sights, extended controls, flared mag well, and extra forward serrations on a 3 1/2"deep carry pistol. It's going to rip you up on the draw and don't be surprised it goes off when you put your finger in the guard a tad early. You asked for it.
This kind of "Hey, that's ok, you learn to live with it" commentary on the net and then claiming Kahr isn't a real good gun isn't limited to just them. Which is exactly why when researching a gun model you need to parse the perspective of the owner to see if they even know which end to hold or if they have any clue what carrying is about. That guns have issues and some makers seem to have more than their share seems to be a fact of life these days, but it doesn't mean they are entirely responsible for the press they get. In some cases it's entirely unjustified when it exceeds reason - and as I have been pointing out, the public doesn't use reason as their yardstick. When it's about guns, life and death confuses the subject with feelings and they go off the rails.
The problem is that there are a lot of men who buy guns and comment on them, but a lot fewer adults. Be careful what you read on forums.
