So I have this itch to own a 9mm carbine. I already have a few handguns in 9mm, and other calibers of course, but in the long run I would very much like to go 9mm across the board. I simply like 9mm performance, price, and availability.
My first thought when I started looking for a 9mm carbine was, I want one that can take handgun mags. So of course the Keltec Sub2k came to mind. Unfortunately this gun is impossible to find anywhere, and honestly it isn't my favorite design, but I would get one if one was available. So I started looking around for others and found the Just Right Carbine, the Thureon Defense 9mm, the Beretta cx4 storm, and the Hi Point whatever. Out of those only the JR and the Beretta use mags that other popular handguns use, i.e. glock or beretta.
The JR looks like a decent design, but it's a little up there in price at around $600 at the LGS, and I have rarely heard a good review about it (other than Jeff Quinn at Gunblast of course). But it does take any size 9mm glock mag, which is great. The Thureon defense is a nice simple design, but it's hard to find and takes a modified uzi magazine, which is not to my liking. I have no interest in the Beretta cx4 storm, and no interest in the Hi Point. Does anyone know of another good 9mm carbine out there? JG Sales, whom is close by, sells a Finnish m31 suomi submachine gun in 9mm and this gun gets amazing reviews for reliability and it takes 36rd, 50rd, and 71rd(drum) mags, which is nice. Any thoughts or opinions on what to do? This gun won't be for home defense, hunting, or anything like that, it will simply be for camping, plinking, and just generally having fun.
