welcome to the family. It’s a rare weapon these days. If your state allows it SBR it. Efile form 1 is the fastest. My main reasons I prefer this weapon over any other once SBR’ed overall length 20 inches, 50 round magazine, and the ammo is lighter in weight then 9mm, 45 ACP., 40 Cal., 5.56, etc. Which comes down to being ammo to carry more rounds compared to the other calibers pound for pound.
