Try not to post in topics that are over a month old unless you have something significant to add to the topic - and even then do so sparingly and because the world really needs to know. The last post in this was over a year ago (and was also a necro like yours). You can easily PM the original poster for this kind of question. (SPU-Nerf is still active on these forums.)
As I see this is your first post, please take a look at the Code of Conduct - you'll find a link in the upper left-hand corner of your screen. The mods here are not very tolerant of people who don't follow it. Read it, live by it, and you'll enjoy your stay here (plus you won't get banned.)
As for your question, you can buy real gun straps at any sporting goods store, and most department stores with a decent sporting goods section. You can make your own from various materials (including belts, leather straps, backpack straps, fabric, etc.)
