What type of holster are you using? Was looking at the belly band ones where you can wear a gun & two magazines. Only negative is it looks like they recommend you wear a t-shirt so the holder doesn’t chafe. I have a Springfield XD-40 but thinking about getting a .38 hammerless revolver that I can keep in my pocket.
I use a Black Rhino Concealment IWB holster.
And from my own personal experience, wearing a T-shirt makes carrying much more comfortable. Even the hybrid holsters (leather and kydex) will rub you raw over time.
No experience with the belly band holster setups. Some of the people that do the firearms podcasts that I listen to have said that they like them, while others have said that they’re not very secure while running. They sometimes bounce in the rig.
Don’t forget the gun belt. Vital purchase for carrying.
