so ive decided against the 586 for several reasons. still undecided between the 66 and 686. personal pros and cons to each. but one question about barrel length...the 66 is a 2.75" barrel and the 686+ is a 3" barrel. now I work commercial construction, and sometimes a 1/4" doesnt matter at all and sometimes a 1/4" will make or break you. will i notice any difference in ballistics in a 1/4"? i dont think there is any way i would, but correct me if im wrong.
