I would like to have an "experienced" person in the NOLA area fit a thumb safety on one of my 1911s. I already replaced the sear and hammer with some Wilson Bullet proof parts so even though I tried to duplicate the filing of original thumb safety, it doesn't fit because the new sear is machined a little different. I would hate to drop it off at a smiff and wait 4 to 5 weeks for a 30 minute to an hour job and would gladly match the going rate of what a smiffy charges.
