I purchased this holster for my Ruger GP100. Great product!!! I am able to conceal my 357 Mag with no problem. Not that I am using it as a conceal carry. It would of been nice if the flap would have been just a tiny bit bigger to keep the hammer from rubbing my skin, but with more use the gun may settle a bit deeper and fix that. I like this holster enough that I just purchased the original QCC holster for my new 9mm pistol. Can't wait to receive it.
