You will find a s/s very different to an o/u particularly as I suspect it is very lighter and faster. I have an o/ u AyA Coral double trigger, cast on that fits me very well and is now my go to gun. Although for many years I did n't get on with it - one day I stopped trying and then just clicked. Also gave a very lightweight WJ jeffery S/s 410 with a nearly 15" stock. A joy to carry and great for short range snap shooting. Also recently got an old AyA no3 magnum with 30" barrels. Hav had it cast on but may need to have stock bent up a touch to raise the comb a bit. But the snap shot a couple of snip last weekend so probably OK. I think a new gun does take a while to settle in and become part of you.
