Might consider how well any quality design in a workable calibre takes speedloaders (as a 'combat' revolver) or the moon clip equivalent. On that basis could be anything from a SW,Colt,Taurus,Ruger to a Webley. Although the Nagant/Lebel/Colt SAA/Adams were certainly 'combat' revolvers, very hard to recharge. So if the grips, the pattern of the cylinder chambers, or the action type compromise that...maybe not a combat revolver (tell that to the Russians) Although with their recent break top .357, if it's put together well...be one cool 'combat revolver...Webley ease of loading, American calibre. With that I'll quit, repeatedly typing 'combat revolver' will give me gunrag nightmares.
