My Siaga 12 does very well. I had a very nice opportunity to use mine in a shoot house a while back. It preformed very well in the multi roomed house. It does have a decent amount of muzzle flash. (event was held at night w/ tac light to simulate home defense scenario) only disadvantage is when I run out of magazines and drums, it's hard to throw a shell in the chamber and slide it home. Much easier in a pump action.
