I did the Pegboard with the hooks in my gun cabinet. Each Pistol/revolver hung by the trigger guard. Looks organized and real handy to adjust to new guns of different sizes. With or without optics and BBL lengths.
Have had zero problems of marking, damage, or ? Use 1/4 pegboard with 1/4 hooks/wire pegs, makes a strong setup if so inclined.
12 or more handguns on a piece 18 X 24 inches. The pegboard can be decorated to taste and or framed to suit. YMMV.
