[aa1911]

Made a drop leg for mine but I mainly just use a Galco I bought for it when I purchased the gun, it's pretty good quality and comfortable.

I think an IWB holster would conceal it just fine, I rock either a full size 1911 or G35 every day and have no trouble concealing either, GP is roughly the same size. Although I don't conceal anymore except where I have to. I have been wanting a blackhawk serpa holster but they don't make 'em for the GP that I see.

But blade-tech is a great company that for certain would make something decent if you wanted to go the plastic route.
