My go to quail gun is a AYA #2 410, 29 " bbl. I have a number of small gauge guns, and always travel with two to three guns. But I always carry my AYA. My hunting companion carries a Arrieta 410, 29" bbl, which is a twin to the AYA #2. I also have a 20 gauge Arrieta, 28" bbls which is deadly on all upland game. All of the above mentioned guns are case colored and straight grip. While Grulla may have a case colored option, the ones that I have seen are not. Try to shoot or see as many of the guns that you are interested in, get a gun that fits you, and good hunting. If you can find a 28 gauge that you like, that will be a bonus.
