I have sold several of my doubleguns, but of those that remain 3 have double triggers and two a single. I don't have alot of experience with the single trigger guns, but choke selection is made when the safety is pushed off. With the double trigger guns the safety is pushed off and the trigger is selected. If there is a time lag my experience doesn't reveal it. I will admit that, for me, having the two types can present a problem. With the double trigger guns I try to pull the same trigger twice and with the single trigger guns I reach for a trigger that is not there. I console myself by admitting that making a second attempt is more unlikely than the first and that the few "doubles" I've made on doves I always have trouble finding the first one down. Course I have even more problems anytime I'm involved with hooks and monofiliment. One thing for certain, you guys really worry me when you start talking about the possibilty of doubling. Probably going to give me a flinch! Perhaps I'll have to start using a pumpgun?
