I hate to admit it, but I use one of those departement store leather belts as my carry/every day belt. As many of you know, these kind of belts generally don't work so well as a holster belt. After clinching it tighter and tighter day after day, I finally had an awesome idea. Mosin sling suspenders. I went and grabbed an extra sling I have laying around, and lengthen it out to almost its full length. Looped the stock dog collar on a 5 o'clock belt loop, and crossed it over my shoulder and looped the handguard collar on the 11 o'clock belt loop and shortened the whole thing to fit. I put the front collar on the second hole and the back one on the first. This thing is surprisingly comfortable, and works great. There are only two downsides that I have encountered so far. The first is the leather piece in front is on the wrong side, and the suspenders are only as strong as the belt loops they are attached to.
I only have one extra sling, but I have a feeling that one of my mosins is about to lose theirs.
