Why? The Kel-Tec Sub-2000 Glock 17 model takes 33 rounds mags and works flawlessly and is very accurate. I own one and would never let it go.Geezer said:I agree. I'd like to see Glock come up with a carbine along the lines of the Kel-Tec Sub 2000. I have had a couple of the Kel-Tec's and they are a lot of fun to shoot.
