When I was young my hunting buddy's Dad owned a Browning Superposed Diana Grade that appeared to me to have been built of magic by wizzards and elves. The engraving was unbelieveable and fit of metal to wood the best I have ever seen. Opening that gun up was like opening some Tolkian-esk secret portal via magic wand. My whole life I lusted after a Superposed over under, and finally when in my thirties I figured I could finally afford one. Well actually, all I could afford was a Citori, but I had previously bought a made in Japan Browning 22 semi-auto rifle off the original Browning design and it was fine. I had to order my Citori through the mail because I lived on Maui at the time and there were no gun dealers that carried that kind of gun.
I realize it's not at all fair to compare an off the shelf Citori to a made in Belgium Diana Grade Superposed, but I was still disappointed in the wood to metal fit and general fit of the gun. It felt heavy and clunky to me, though I shot it very well with it, hitting 23 clays in a row before missing one, then hitting the last of 25, and that was my first time ever shooting trap. I moved to Montana with that gun in 1992 and used it for duck and pheasant. I grew disenchanted with the bulky action carrying it afield and it would occasionally freeze up on me in the duck blind, plus I occasionally had misfires which means you don't get a follow up shot because there is only one hammer that cocks on recoil.
So I ended up trading it in on a new Ruger sporting clays model, 300 " barrells. I love that gun! I have used it every year since 1993 and it has never failed me, though after umpteen thousands of shots the detent spring on the safety wore out and had to be replaced last season. Now my gun smith hates the insides of Ruger Red Lables and he adores Citoris, but from a functional standpoint, for me I prefer the Ruger. I occasionally switch triggers, and I haven't had a problem with accidently getting caught in between, but actually I don't find selective triggers that practical for fast shooting, I much prefer double triggers.
If you hit well with the Ruger and like the way it carries, why not invest a hundred dollars in a fix with a gunsmith. I don't remember now from your original post, but do you have this problem even if you don't switch barrels? If not just use it. I have seen various trigger selectors, the Browning, Ruger and Beretta, and I like the Ruger as well as any of them, the Barretta is hard to do with gloves on. As a piece of fine gun design the Ruger probably scores slightly behind the Browning and Beretta, but for me in the field I like it.
