I bought a cimarron1911 impulsively. After the first range trip I noticed just how ugly and mistreated the rear sight was. I bought a 1911 MGW sight pusher and a Harrison Design retro sight. I just can't get the sights to budge with that device. This is what the sight looked like on the brand new pistol. My next step is to get a new brass punch set and try removing it with controlled Brutane.
