This is for the most guns in the smallest area in the now closed gun shops category.
Ludco Gunshop in Parker had a heck of a selection. The day I was in there long rifles were stacked 3 and 4 deep along the walls and pistols were hanging on wires from the ceiling. I don't know if you could find what you wanted but it probably was in there someplace.
Probably the most guns for the smallest square footage anywhere.
I went in their once and was just in awe! Guns hangin from the ceiling on strings, long guns leaning against the walls 3-4 deep, scopes stacked 4-5 high in the case and holsters everywhere. Brand new pistols were stacked on top of one another in the case. I could hardly move around so it was so full of everything. To bad it was raided....
