Trap, skeet and sporting clays all have there variables, one of them being gun malfunctions. You have enough to do when you step on station than wonder if your gun is going to go bang.
When I first starting shooting clays targets I used a Win M-12, In 1974 when Win. brought out the Super X M-1 semi auto I bought one for trap. Then the skeet version for skeet. The skeet version had gas port sizing issues, and at times wouldn't eject a casing.
I was at a shoot in the states and on my squad was an older gentleman who among other things was world champion in 28 ga. The SX-1 had jammed twice on that round, and I wasn't amused. At diner that night he was sitting beside me and passed along the wisdom that I mentioned above about having enough to do on station than worry if the gun is going to work. He advised me if I was going stay at the clay target game to go out a buy a good quality over and under, learn how to shoot it and don't look back. He related how he had come up through the ranks shooting pumps and semi's and settled on a Browning 4 barrel set.
I took his advice and traded the SX-1 skeet version in on a Win. 101 as it fit me better than the Browning Citori. I later bought a 101 in .410 as well. Over the years I poured thousands upon thousands of rounds through those 101's without a malfunction. I have also owned a Ruger Red Label which was one of my pheasant guns, excellent guns. When I retired from clay targets I was shooting a Classic Doubles 12 ga, skeet version. Basically a Win 101 with all the bells and whistles packed in a fancy luggage case, which I still have.
So I pass the advice I received as a young fella on to you. If your going to stay in the clay target games, buy the very best over and under you can afford that fits you well, you will never regret it. Plus you will never pick up another hull of the ground again.
