I don't think think it would be worth the trade. 2-3 reloads a stage vs 1 draw. SA trigger on decent CZ or tanfo isn't much worse than a 1911. There is only one draw per stage, wouldn't be worth what you made on a draw vs 3 slower reloads and risk bungling one.
If you let 2011's in (and that isn't really rhe OP's question) there would be no reason to run a 1911, you'd have your trigger and your tapered mag/bigger opening.
I am going to goof around with 9mm SS this year. I am pretty sure I will be able to beat myself with my shadow. I don't think I could with no magwell. I am speculating though, for now.
