I'll stick with my Sig.
I haven't read all previous posts so this may be reiterating points already made but I wouldn't make a blanket statement that I would trust my life to any gun by any mfg without shooting it for recreation first for long enough to convince myself it will function properly when I need it to. I wouldn't trust Sig Sauer, Springfield Armory, Glock, or any other highly regarded mfg until shooting the gun long enough to satisfy myself it functions properly. If I can put 200 rounds through it with minimal hiccups, and they are merely hiccups that are common failures cleared easily, I would trust it. Another thing to consider is mags are more often than not the culprit, not the firearm itself.
amazing... about 33% of poll would not trust a Keltec
below is a link to instructions for a Keltec fluff and buff

Kel-Tec Fluff and Buff
by Chandler Bates III
A few KT's do not work real well right out of the box. This happens with other modern, light, compact weapons also. Malfunctions discourage owners from depending on weapons. However, the design and other characteristics of the Kel-Tec � the reasons you bought it in the first place � are excellent, so you need to give the gun its best shot at pleasing (protecting) you. Performing the following "Fluff and Buff" procedures, then lubricating correctly, before you ever fire your gun, will increase your chances of having a really good running gun right from your first experience.
Check out the following URL's at the Kel-Tec Owners Group web site for suggestions on disassembly/assembly and more specific instructions for individual procedures. Working on the KT's is a joy. They are really fairly simple for the mechanically minded, handy people. Having the right tools and supplies helps, of course. These include:

So after purchasing your guns you expect it to be standard to need to perform the finishing operations not done at the factory? Okaaaaaay.
If a gun mfg was to say "Here is "Gun A". It is low cost but is so because the finishing operations typically done by most gun mfgs are left for the end user to perform if desired." Then I would see it as being OK as you bought the gun of the understanding it required more work to function properly, and you as the buyer were willing to do that work to save a few bucks. In this economy I certainly don't put it past anyone including myself.
However Keltec doesn't do this. They say "Kel-tec CNC Inc. is committed to the development and production of high performance firearms" taken verbatim from the front page of their website.
