Did you watch the outdoor channels Wednesday at the range line of shows this week? One of the shows was all about some big silencer shoot off in Lavonia, Georgia. They talked about how you have to pay the $200 fee for the stamp to have a silencer and fill out the paper work. They had a silencer on a browning high power. The guy who put it on said he was surprised it worked so good because usually you have to replace the recoil spring and tweak a 9mm to get it function with a silencer. He said 45s take silencers better. They had companies there that make the gun and silencer an integral unit. Very cool. The guns look like they have a reallly heavy barrel, but the silencer is just built into the gun. I had read on the internet that to have a silencer that along with the $200 stamp you had to have the cheif law enforcement officer of your area sign off on the form, but They never said anything about that on this show. There was a whole bunch of people with snipper rifles and machine guns with silencers on them.
