Guys -

I need some help in buying a gun belt. I think I know what brand I want, but I can't figure out if I should add 2 inches or 4 inches to my waist size for the belt.

I'm looking at bigfootgunbelts.com for a black leather gun belt for my S&W Model 629. Holster type is irrelevant for this thread but I have a good one. That belt supplier suggests adding 4 inches, but I'm concerned it will be too much.

Would appreciate all opinions - and thank you.
