Apparently this is why you have been seeing more of these guns and will hopefully keep seeing them. I want to pick one up one day, but not above MSRP when i can barely even use the factory iron sights.
They streamlined the processes of making the Sub2000. Instead of having around five to eight different models of Sub2000, kel-tec is only going to have two. The Glock mag model and the S&W M&P model. The Glock models will only take Glock mags while the M&P model will have a removable mag catch that that can be replace to be able to take any of the other magazine types. M&P, S&W 59 series, Beretta, Sig. I thought it was pretty cool. Hopefuly someone here will get one and report back on how the new system is.
