I made one of these for a 6in 44mag over a year ago for a young man that is a timber cruiser up here the Olympic national forest. He carries this gun almost daily for 8 to 10 hrs a day. He's come back for several axe sheaths, slings, other holsters,etc and always brings this one so I can see it. The plastic buckle has held up fine. It's not holding up the pistol, it's holding it close to the chest. See my post "one year later".
