Does it have a trigger?
Does it expel a projectile?
LOLEasy, semi auto.
I'll shoot my revolvers more when I'm old and slow and can't bend over to pick up the brass
Both, except when it comes to cleaning afterwards - then the semi wins hands down.
Sure you don't have that backwards? A revolver doesn't have to be taken apart to clean after shooting. Or at least mine don't. I guess the most "take down" with my wheel guns is removing the cylinder in my SA revolvers.
