Universal 1911 slide mount??? not! - Vortex Razor Red Dot Handgun Slide Mount

The adaptor billed as "fits any 1911" to adapt the Vortex red dot sight is just plain wrong. I was fairly sure it wouldn't work, but needed a starting point to machine parts to make it happen. 1) the plate did not fit to the Vortex. 2) The holes in the Vortex were too small for the machine screws used in the adaptor. 3) The adaptor did not fit to the Springfield 1911 - 9MM that I own. I made it all OK, but used a lathe and mill and hand fitting beyond most folks' capability. It might work better on some 1911's, but I can guarantee they (owners) would be perplexed and 2 of the three problems I encountered would still present a problem.
