0n0w1c, where are you located? Maybe we can put you in contact with someone local that can show you and, most likely, let you shoot different guns and then you would have much more information to make a decision.
B_Koes, is right on target. Most folks prefer the mid grip for creedmore, some use the rear grip for dead frog, and the rear grip is the most popular for Unlimited standing.
Eye relief quickly becomes an issue with a rear grip in creedmore or dead frog. For open sights it doesn't matter.
I personally use the mid grip in creedmore and use a contender for US (and everything else but revolver.)
Good luck on your decision and welcome to handgun silhouette.
