I shot a 28" 16 ga AyA53 - SLE, side clips, hidden 3rd fastener - for about 5 years and wish I hadn't sold it. A very sweet, nicely balanced and handsome shotgun. On the other hand, the 3rd fastener broke on a pheasant hunt during the first year I had it, and I couldn't open the gun. Jack Rowe repaired it and I got the gun back pretty quickly, but I still remember walking a weedy ditch back to the car with no way to reload and having my springer flush two nice cock birds.
I'm a sucker for a nice 16 gauge, and wouldn't say 'no' to an AyA 53 in 16 gauge for the right price. I lucked into two Ugartechea 16 gauge guns this year, a model 116 and a model 75.
