I have it turned sideways in the photo below, but a few years back...I bought a front/rear bag from "Dog-Gone-Good" in the US, filled them with polypropylene "re-grind" from a local recycler, and they've been performing superbly ever since. If I remember my conversation with the owner, he also makes bags for outfits like Brownell's. The ones I have feature black suede/leather on the inside for a nice, soft, but naturally grippy hold on the gun. They've become one of those affordable, but immensely effective/useful parts of my kit that just do what they're supposed to without issue, every time. I can't see every using anything else, and have recommended his products to a few people.
