Dave--I shoot them as often as I can. The G22 is relatively new, but it gets its turn at the range 2-3 times a month. The Mossy gets more action since adding the RD sight, but during the warm weather months. Use it to bust clays and also put slugs thru paper.
Aviz--It has so far. It's still new on the gun, but seems to hold up to slug shooting. Any reason it shouldn't? It's advertised for pistol and shotgun. But, for 25 bucks at Gander Mt., how can you go wrong? If you can recommend something more durable, maybe I'll upgrade if this one ever breaks.
