Marketing a new M1 Garand would be nice, but I suspect there would be an equally lucrative market in M1 parts made to military specs. There are lots of M1's out there in need of replacement parts, and the supply of GI parts has dwindled down. Ruger's Mini 14 offers a M1 carbine like rifle but in an updated caliber that isn't impossible to find. I imagine that CZ is busy designing new guns to add to the Colt line, but Springfield could get a big jump on the competition by offering a Hi-Power design in .45 cal. or 357 Sig.
