GP100 & Simply Rugged holster with Chesty Puller

[captainjack]

I have a SP101 and a Simply Rugged Silver Dollar Pancake with IWB straps and love it! Now I am thinking of purchase, a new a GP100 4 inch with a Sourdough Pancake holster with the Chesty Puller straps. I am interested in using it in the under arm position. Does anyone have any experience with the Chesty Puller straps in this application?
