I have the exact same setup. UMC frame and Colt Slide 1918 date on the frame. I will pm you some picsUnfortunately no, sold the pistol with the colt slide a couple years ago for way less than it was worth but way more than what I paid for it. I had it for about 20 yrs so I decided it was time to let it go and let someone else do the leg work. Do you have a slide???
