A Kel Tec Sub2000 in 40 S&W followed me home over the weekend and it came with one 22 round Glock mag ... which is of course not nearly enough mag capacity for a home defense weapon. I would rather have three or four fifteen to eighteen round mags than a large 31 rounder. But, like an idiot, I bought a Korean (?)(KCI) 31 rounder which will not feed if loaded past the thriteenth round. I'm going to take it apart and file out the roughness inside then see if it works. But in the meantime ...
From what I read, these should be OK for the KelTec Sub2000.
Good luck.
I’d love to shoot one of those KT sub 2000.
Please come back after some range time and let us know how you like it.
Search for “KCI”, “Khan” or sometimes called “Kahn” at your favorite gun catalogs. They are South Korean made to spec of the Glock mags and should sell for around $13.99 which is what I paid for mine but my seller is sold out.
Sportsman’s Guide has them but are way over priced even if you join their “club” for the discount.
