I know what you mean,1 1/2x3inch tubing,it conseals everything.Also mine will sit on your shoulder,not in front.It will work great for breaks also,just mack the frame longer than the barrel or the same,and it will deflect ALL the gases away(conceled in the frame,muzzel end open).Also both grips will be at 45 of center line.As long as i'm doing it,it will fit right not like ones made.It's like everything else today,as long as it looks good someone will buy it.
