How prone to doubling are the single triggers found on the CZ/Huglu shotguns? I've heard here that they'll double "every time", but can they be made safe to fire in a DR built for .450/400? That would be the maximum size rifle I would have any interest in owning and shooting. What about in a medium bore like .400/350? There is a nice looking 12 gauge CZ that is available, it even has a cheekpiece stock, but it has a single trigger.

Thanks.
