Good information to know. Thanks!
Of course, if you have another hundred or so to spend, the KelTec sub2000 in Glock, with a Glock handgun to accompany offers the same benefit. I reccommend the 40SW in Glock 22 or 23 configuration. The 30 round mags from Glock or KCI (Korean) will work in both handgun and carbine. In a pinch, the Glock 40 cal and 9mm mags can be interchanged, with a slight crimp of the feed ramps going from 40 cal to 9mm and slight spread going from 9mm to 40 cal. The frames of the pistols are the same size, with the barrels being the differnce.
