One of the best ways to carry any gun,especialy big guns is with a quality IWB holster.
I have used Milt Sparks Summer Specials for 1911's and S&W N frames for many many years.
Hint, buy your pants 2" bigger in the waist.
If you must use an OWB holster look for a quality pancake style, as it has the belt loops on the sides of the holster, not om the back, so it holds the gun high and tight.
I am wearing a S&W 44 Mag Mountain gun in such a holster right now.
Normally I most often wear a 1911, but durring hunting season I switch to my 44 Mag.
I have never had it spotted under a untucked button down shirt.
Just a few days ago I ate lunch in a resturant, in one of the top 6 metroplexes, carrying my Mod 629, right next to 4 Police Officers, and my gun was never spotted.
Let the record reflect I was legally carrying.
