I tried several and it didn't work because:
-revolvers do jam.it's airsoft.
-being double action, there's a lot of effort on parts and especially the cylinder lock that will break because it is made in pot metal even in supposedly quality revolvers like Tanaka's
-you will spend your time reloading
-most revolvers aren't very powerful which means you really have to hope your target will call their hit.
-powerful revolvers (like wingun) are too powerful (over 400 fps) which puts them above cqb field limits.
