I've shot a couple K-20 guns that were a real dream. Also a MX-20 framed gun with a 28g long barrel would be slick too.

I agree the 525/625/etc. long barreled version would be nice. I think I'd go with a 32" gun. I have a 525 in 20g/32" that I have a hard time missing with. I just think the trigger pulls stink and will need work.

I've looked hard at Guerini guns a number of times. They seem like they are a little better fitted than a Browning.
