They're just furthering a new market on the 45GAP. From what I've seen, it never has really taken off. This is just another attempt. Don't get me wrong---I'm a Glock man myself. The 45 GAP isn't really new either. IMO, the 45 GAP, the 357SIG have less of a following than the 10mm. The real numbers are probably still being deciphered. Propagation will occur only when there is a niche to be filled. Now on the other hand---the new 5.7 round might really take off.
