Been carrying for about 3yrs and have used a IWB holster since day #1. Took about two hrs. to get used to it. The holster is from MTAC http://www.comp-tac.com/product_info.php?products_id=95
(about the same as Crossbreed).
Invest in a good belt also. Have never had a problem with it. I am considering this all leather holster from El Paso Saddlery http://www.epsaddlery.com/pc-226-72-summer-cruiser.aspx
My wife qualified a few months back and had to use whatever type gun she might carry, so she qualified with both a revolver and a semi auto.
Don't think you'll have a problem, good luck.
