I bet most of us wish our BUG's were as light as cell phones. Lol.
A light set of ankle weights with all the weights on one side of the ankel might be a better example.
Borrow a good ankle holster from a buddy and try it for a few days. You might find your blue jeans wont fit the bill anymore unless you wear boot cuts. Suit pants are in,docker's,slacks etc.
Pants need to be long so when you sit the holster wont show so wearing floods are out.
I'd make sure a thumb strap is used also and you buy the correct holster for your pistol. Its very embarrassing when your gun falls out on the floor when you run,jump or trott. My partner got into a light skuffle with a punk and his BUG fell onto the floor. Lucky the store manager was there to retreive it and not the punks friend !
Good luck with your choice of back up carry.
