I also have a Kel-Tec Sub 2000 that takes Glock mags. It's got the feel and ergonomics of a cheap, crappy, plastic gun . . . but, I really like the gun!

The only things I would add is that you are not supposed to use aluminum case ammo (CCI Blazer) with it. Also, the only ammo that I remember having problems with is CCI Blazer Brass. I have no idea why but, I regularly get failure to extract/stovepipe jams with it. I have shot a lot of different ammo and can't remember having any problems with anything else.

It not my first choice for a last resort SHTF gun but, it's a good choice for a trunk gun.

By the way, below are some chrono numbers I have that will give you an idea of the kind of velocities you will get with one. I had posted this on various forums a long time ago but, I thought you might want to see it.

Here are some of my recent tests out of a Glock 17 (4.5" barrel) and a Kel-Tec Sub 2000 carbine (16.1" barrel). I used the Kel-Tec because I was curious to see how much velocity would be gained by a longer barrel with the various ammo that I tested. Everyone has a theory but, one test is worth a thousand theories.

If it matters, testing conditions were about 40 degrees farenheit. All testing was done on the same day.

I am by no means an authority on ballistics. I welcome all feedback and comments.
