I have owned a KelTec Sub 2000 for years. I own the very old first gen, 3rd gen Smith and Wesson magazines, model. (Currently has the mag catch to take Sig P226 magazines). I never really warmed up to the first gen model. Probably because the front sight doesn't appear all that durable and is flimsy. I just bought the new Gen 2 model, 9mm, takes Glock 19 magazines. Put 400 rds of 9MM NATO through it and 100 rds of Federal 9BPLE 115 +p+. No jams. No issues. Works great. Feels good in the hand. For whatever reason, I seem to prefer the 2nd gen model MUCH more. I actually really, really like this model. So, its tested, confirmed good, and going in the get home bag with the Glock 19 pistol.
