Bought the mini-clip for my Mossberg 500 to shoot the mini-shells.
The clip fit in snug and seems to holdup well, I’ve cycled and shot a few boxes without any misfeeds or loading issues. The mini-shells allow me an extra 4 rounds in the shotgun. The only issue I can see is that with the mini-clip being black, if it falls or gets knocked out in high grass or underbrush I might not be able to find it. A hunter orange or some other high vis color would be a good option
