iwb holster for 4 inch revolver?

[old fart]

i have a ruger police service six 4 inch barrel, and was wondering has anyone carried a similar gun iwb? i have a chance to get a choice of two holsters, one is thin leather and the other is thicker leather both iwb holsters. the thin leather isn't but the thicker leather is molded to my gun. i have a pancake holster coming in but thought in summer a iwb might be better if it can be done. i'm 5`6" and 160lbs, has anyone carried a gun like this iwb and it go ok? just want several carry options in case different situations arise. thanks
