what are the main differences between the CVA Accura V2 and the Optima. I thought it was just the barrel on the V2 being the Bergarra. However, I could have swore I saw something that stated the Optima came with a bergarra as well.

PS. I'm looking for something that had hold a group. I'm currently shooting a TC Encore Prohunter with belm TC trigger work and over sized hinge pin. I've tried everything from black horn to whitehots and every bullet under the sun. cleaning between shots etc. and this gun sucks!!
