The reason one observes few A-5's on the clay bird fields has nothing to do with reliability....
Gas-operated autos such as the 1100, 1187, SX-2, etc. have less perceived recoil. The A-5 "doube-shuffle" is less condusive to clay bird shooting. I've owned an A-5 for 20+ years, during which I've bought, used, and sold several gas-autos. But my 1951 A-5 just keeps on ticking....
As far as beauty goes, I think the A-5 is "handsome" and "unique," somewhat like an engish bulldog. Not beautiful, but pleasant to be around.
