I picked my Huglu up from Gander Mt. today and talked to the 'gunsmith'. He said he wouldn't work on these triggers because of 'liability' reasons.
Triggers on a shotgun should be around the 3-4# range for optimum use. Some SxS's have double triggers, one for each barrel, and some have a single selective triger that can be set to which barrel you want to shoot first. Mine is a single selective trigger. O/U's almost 100% of the time have single selective triggers. I can use them up to the 6# range but after that it is hard to get the trigger 'slapped' and have it go off without a serious flinch of the gun, thereby missing the target. 98% of my shooting is clay games with a shotgun, the rest is small game and the occasional deer.
The reports I have seen were in different venues on the internet, most were browsing
www.shotgunsports.com . WildAlaaska had some choice things to say about them on the High Road.org.
For what it's worth, I would never buy a Huglu for a main gun, the only reason I got the SxS is because it was unique, and something I wanted to play with, and I didn't have a SxS. I have 20 other shotguns to choose from and all of them probably better in some sense. Some much more expensive many less expensive. For a first shotgun and overall value in a shotgun a Remington 870 express is hard to beat,
or a Mossberg 500/590. I don't have an Express version but have 2 of the finer Wingmaster 870's.
