Kokapelli,
The source of my info is from reading KTOG.org and personal experience with all four calibers of the Kel Tec product.
The Kel Tec gunsmith posts there as do many other Kel Tec devotees.
Go read the threads there about these fine weapons, even the owners bitch to high heaven about the problems that they have.
Buy any gun you like, I recommend Sigs, Berettas, Glocks, Smiths, Walthers, not Kel Tecs.
I just sold my 380, it went from reliable to FTE and light striking all in one 30 round session with ball ammo.
I don't need a gun that needs to be babied to keep it working, I need guns that work when filled with lint, dirt, etc.
I carried the same Glock 17 for 11 years as a duty weapon, no malfunctions and no Kb's.
Glocks have a serious problem with the 40sw/357sig and 45acp cartridge. They like to blow from time to time. That sucks and effects their reliablity permanently.
There is an inate problem with the 40/357 cartridge, it is poorly designed with weak cases, particularly at the web.
Glock has a problem with loose chambers and poor case support. The two combinded leads to disaster. That's one of the reasons I carry multiple back up weapons.
The 9mm Glocks do not share this problem, nor do the 9mm Kel Tecs.
I still trust them more than I do a gun that won't feed reliably.
I know well the problems of the Glock, we had an officer using Blazer ammo Kb his Glock 22 a few months back. We are banned from using Blazer in our dept issued weapons.
I am tweaked that out of the four Kel Tecs I have owned, the only one that worked is the P32 that my wife still carries.
The others have been a waste of time and money for me. Guns should work correctly out of the box, not after a fluff and buff or a trip back to the factory.
I do wish Kel Tec's performed better for me, I would still own them and carry them, but after a 75% failure rate, I will carry my Glock and a revolver or two instead.
