I am looking for some basic advise on silencers for the Glock 17. Any suggestions on where to get a threaded barrel from and any good or bad experiences with a silencer on a Glock 17? I am looking for a silencer that I may be able to share with a couple SMGs (M11/9, M10/9, UZI, or AR-15 with 9mm upper) but I know making the glock work will be the biggest challange... I am also curious about any special problems with the can blocking the sights... I would like to have a parctical supressed G-17 when i am done if possible ;P Thanks!
