Lol... it's worth it because you get tough guy points for having a suppressed 1911.I don’t know what link you’re going to because when I check silencerco’s website I no 1911s listed in the drop down for the threaded barrels. And either way, even if it’s $220 plus $100 for sights I’m still getting into the same range as buying a new gun, I don’t see the point in it. I’m not gonna pay more than 50% of what I paid for the gun to add a threaded barrel.
