Greetings,
Have you shot Bullseye competition before? The reason why I ask is that a revolver is a little more un-wieldly on the firing line when it comes to loading and emptying the spent cartridges. It can be difficult to not "sweep" the line if you're not careful when you drop the cylinder. The RSOs get downright grumpy if you sweep the line. I watched a guy get booted off the property during a match because he just couldn't get it right.
Also another consideration: Can you shoot rapid fire(5 shots in 10 seconds) double action style? I think this alone is why most of the Bullseye shooters have gravitated to semi-autos. Reloads are quick and easy and it's easier to stay on target just having to pull a 3 1/2 lb. trigger.
Whatever, good luck to you in your Bullseye comp.
In regards to bullseye also, you only use one hand to hold the gun in all aspects. "Son, they don't call it a hand-gun for nothing, my instructor chided me."
