Never;
I've been dealing with Milt Sparks leather for a number of years now. I've never had a problem or been dissatisfied in any way. You can call them & talk to Tony, Milt isn't with us anymore, & get things the way you want them. For what it's worth, I've been carrying my USPc in an Exec's Companion IWB from them for about 10 years now. It's hung on a Milt Sparks belt also. Holster's just fine, the belt seems to be getting shorter however, but it still works. Oh, and that's not my first, or last, piece of Sparks leather either.
I believe they have an on-line catalog also, but if you want to call, they're in Boise Idaho & in the phone book.
