These days, they are badge-engineered Gamos and not highly thought of. I have an older Birmingham Supersport that is quite nice. Newer ones, less nice.
No open sights. Otherwise a top choice, of course. I also thought of the Webley Vulcan, Stingray, Xocet, but discounted for poor/average triggers and cocking effort. Maybe the old lower-powered Victor might be an idea? But I'd still prefer an HW or a D27.
