I posted something similar to this on another forum awhile back. It's just seems to be a tactic I've seen many shun. It's too important to neglect. I think it is a must in training to devote a significant amount of time learning to shoot with only one hand. Strong side and weak side. If you don't do this you should start. It is very likely that you will not have either time or the ability to use both hands at the moment that the ball drops.
I hope I'm not beating the proverbial dead horse here. It's just that SD is something I take extremely to heart. I' hate to hear about one of the GG going down because he/she couldn't control their handgun well enough to make COM hits shooting one handed.
It's good to practice everything you do with two hands with only one hand too.
