Video- http://www.youtube.com/watch?v=qNMLO18kl98 Recently a Colorado police officer contacted the BATF to inquire about the legality of firing a pistol from the shoulder when equipped with a Sig SB15 brace. It doesn’t come as a surprise to me that the ATF said it’s perfectly legal to shoulder the “not-a-stock” device when attached to a pistol. I knew it was legal to shoulder the SB15 when it first hit the market as I had researched it years ago when AR15 pistols became popular and people were shouldered the stumpy extension tubes and firing them as if they were really short stocked rifles....
