Richard - I bought the McD on consignmet at a gun shop/range. At the time I had over 30 Kimbers in addition to my Wilsons, Les Baer, STI's and others. The last thing on my list was another 1911. Ah, but the manager knew me well. He handed me the gun and some ammo and told me to go shoot it. After one mag, I knew that THIS gun was built for me.
Tack Driver? I'd put it up against my Customs listed above.
If I kept the original S&M & Assoc invoice, I don't know where it is. It was a Full page of listed work.
KJ - next time I feel industrious and have the time to get into the buried safe, I'll take a pic.
