Had both. The BSS was the 12ga. non-selective trigger. I used it on ducks for a couple of years. Absolutely reliable but a complete club. The 23 was a limited production model with flush chokes and the action was filed like a Mod.21. The dynamics were better than the BSS but not good. The 23 had a recurring trigger problem but it's so long ago I don't remember what it was. In any case they both went down the road and I don't miss either. If I had to vote for one it would be the BSS. The 23 was better finished but was unreliable.
