I have a Miroku MK70 in 28 ga w/30" barrels and I love it. Fixed chokes and no ports. I also have a Citori Feather XS Sporting in .410 with 30" barrels, fixed chokes and no porting. Liked it so much that I went looking for the same gun in 28 ga, could not find it but did find that MK70. I think I prefer the balance of the Feather XS with the aluminum frame vs the steel frame on the MK70, but hard to tell for sure because of the difference in gauge and barrel weight. The Feather XS (in the U.S. at least) came unported in .410 and 28, but only with ports in 20 and 12, and I hate ports. So, in a 20 ga I'd go with the Miroku over the Browning. But my 20 ga 30" is a Beretta 687 SP-II, and that would have to be my first choice in a 20ga/30". My 12ga 30" is an old Miroku, and I also have an old Citori Field in 12/28". The Citori is solid and a bit heavy, but has 3" chambers. The Miroku is prettier and better finished, seems a bit livlier, but has 2-3/4" chambers. It's a crap shoot.
