I carry AIWB with 2” snub nose revolvers in a Cardini nylon holster with sweat guard. You are correct about the hammer issue. With the sweat guard you don’t feel a thing.
I am 6’4” and 280 with a slight belly extension. Can wear my gun all day standing,sitting,any position with comfort.
I practice draw with snap caps. The only time the gun would come out of the holster is if it had to be used.
If I need to remove the gun,I remove the holster with gun inside.

Be SAFE and Shoot often!
