My primary wadcutter match .45 has an Illusion Red Dot scope mounted in Tasco rings on a Weaver style base mounted directly to the slide. It's held up for over 10,000 rounds and got me into the NRA master class, so I guess the combo works. The Illusion 1" scope is not readily available now days, so UltraDot would be my choice. Discounted, they can be found for about $100.00. Note that the Weaver style base is a specialized base, and has a slight taper milled into it. Also, mounting a scope on the slide means you have to adjust you recoil springs to your load, and the loads are only light target loads, not hardball or other high velocity/high performance loads. The balance is so fine that you may have malfunctions in cold weather if you don't bump up your load slightly. It will require a firm, consistent grip to prevent catching cases, but then again, that the nature of the 1911 in general. The extra weight on the slide slows down the recoil cycle, but for me the firing cadence was much like my hardball/Service Pistol cadence. You should also add an extended ejector. The scope base and extended ejector can be gotten from Gil Hebard Guns, 125-129 Public Square, Knoxville, Illinois 61448. I've dealt with them for 30 years and they have been consistently good folks to deal with.
