A revolver doesn't have a grip safety. Also, a cocked revolver typically has much more of a "hair" trigger than the single-action 1911. Most 1911s have a ~5lbs trigger pull that still has a little bit of take-up before it breaks. Revolvers usually have NO takeup, and are lighter too. To answer your question, hell no I wouldn't carry a revolver in SAWould you carry a DA revolver in a holster with the hammer cocked...and believe it's safe?
I'm not necessarily concerned that I will accidentally pull the trigger once my finger is placed on it. If I have to pull my gun out, it IS going to be used. The length of the trigger pull doesn't matter at that point.
I do see the point you are trying to make though..
