mp5/10 and mp5/.40

those would be nice to see around, i suppose the adv version would do if the rounds hit harder then the standard 9mm. some new glocks to, like the g21, love that gun, .45 cal, and the glock 20 in 10 mm, ooooo. ooo , ooo how about a saiga shotgun!, chamber it in .410 if you want to bring down the advantage of semi auto shotgun
