Well Jeff, you are going to get as many suggestions as there are holsters.
My suggestion for OWB is a Sam Andrews Hybrid Saddle Holster. www.andrewsleather.com
For IWB either an Andrews McDaniel Holster w/body shield and cross-draw options or Gary Brommeland's Max Con V. I'm waiting delivery on my Max Con.
I have 2 hybrid saddle holsters for my 4 and 5 " 1911's as well as a pair of McDaniels for them as well.
One thing to remember is to spend some money on a good belt as well. A good holster is only as good as the belt that supports it.
