In the winter months I carry either a 2 1/2" Model 66 or a 3" Model 686+, The difference in weight is only about 3 oz.
The keys to carrying a handgun like a 2 1/2" Model 66 that'll weigh in at around 36 oz loaded comfortably all day long are:
- a well made double thickness leather gunbelt - ideally with a polymer stiffener sewn between the layers; and
- a well made IWB holster.
I use two holsters depending on the need.
The first (left) is a Wild Bill's Concealment Covert Carry. It's a tuckable design that I use with a tucked in shirt when I have to wear one. Wild Bills is located down the road Garner NC.
The second (right) is an IWB or OWB (reversible clips) Next Holster Guardian holster that is not tuckable, but very comfortable. Like Wild Bill's, the company is located here in North Carolina and everything is American made by actual Americans.
My understanding is the company was founded by a guy who left WBC due to creative differences, and it's a win win for us as you do get two different approaches, both in very comfortable and quiet all leather construction, as opposed to kydex or hybrid leather/kydex.
The Guardian is flat when it arrives, but in a couple days it will be molded very nicely to your hip contour.

Both of the above holsters will stay open inside your waistband when the holster is removed. The WBC Covert Carry uses a double thickness leather with insert approach, while the Next Holster Guardian uses a lower profile approach where the square blocked front of the holster keeps it open.
The rear, single clip design of the WBC Covert Carry creates some space that works well for a slip over speed loader carrier to be carried in front of the holster, where it is very well placed for the FBI, Universal or Stress Fire reload techniques.
