Hi everybody,
I believe that a lot of gun novices buy Kel-Tecs because of the price. Therefore, IMHO it is probably limp wristing that is the bug for most Kel-Tec newbies with problems. Getting the best matchup of ammo, recoil springs, and mag springs for a particular shooter's needs will help. Big guys with years of shooting experience will feel differently about a Kel-Tec than a petite lady on her first trip to the range. Wolff Springs makes a recoil springs power pack that is quite helpful at finding the right fit for your ammo/shooting style.
Wolff springs Also, a lot of problems I believe come from the mec-gar mags that need a little lip tweaking, or a spring upgrade, also from Wolff.

KTOG is simple for the most part, and in most cases requires little more than patience and some 400 to 600 grit sandpaper. Of course you can do a lot of cool mods on your Kel-Tecs if you want to, but that's more for feel, than for reliability.
Of the hundreds of thousands of firearms Kel-Tec has produced, we have heard from almost 3000 owners or prospective owners at KTOG. Some people come there seeking answers, and others just want to say what a fine pistol they've purchased. The Kel-Tec "problem" is vastly overstated. BTW, as far as customer service, I recently bought a P-40 conversion kit (used) for my P-11, that also came with a P-40 mag. The P-40 mag spring was totally messed up, so for less than five bucks including insurance I mailed it to Kel-Tec for an exchange for a brand new one, no questions asked. Their customer service is friendly, and they go out of their way to make the customer happy. Just my 2 cents. Regards, Keys
