Questions about my S&W dual carbine,

No it doesn't have a 1/2" B/C gap, its .005, Unblued barrel shank doesn't show up well in photo because of white background in frame window area is all.

No you don't need a welders jacket, although I do run a long sleeve shirt. Think about how you hold a fore stock, your elbow is dropped down and is under the frame itself and some distance from the gap. Gap blast has never bothered me one bit. Make a big tube.about 3" in diameter of construction paper or card board, stick a revolver in it and check out the blast pattern sometime. Nothing on the bottom 30 degree arc because of the bottom of frame blocking it.

Why a 45 colt/acp cylinder when it started as a 45acp?
A: because I could
B: because I love 45 colt and heavy slugs. White tail in the brush anyone?

Here are some generic mods
A 8 3/8 25-5 cut to 5" and fitted with a reamed 44 mag cylindeer to get a pinned and RECESSed

Here is a 1917 with a chopped 1950 barrel, adjustable sights, round butt cut down grip frame and bobbed hammer. Shroud was relieved to retain big ejector knob
