I profiled the back like a 3" 20ga shell, turned the front to well clear the barrel in front of the chamber, crowned it, then chambered in 9mm.
GTG. Like having a 9mm carbine, but none of the weight.
Anyone that owns a 357 handi rifle knows you can't get it much down under 8 lb. my 20ga ultralight is like 5.5.
