I’m sure this has been asked before, but can’t find it in the archives:

I’m finally graduating to putting red dots on my pistols. I have no idea where to start to find the best slide mount options for my 1911s. 

I will be using sig romeo5s to start and upgrade to aim point micros as funds allow. 

Please share your experience for options. I’m understanding I could drill/tap and add a rail, could have a cut out milled into the back of the slide, etc.

Thoughts?

With your plan on sights a slide mount would be your best bet.  I prefer Rock River Arms because it's more versatile, more cross slots to mount your dot.  There is also Jon Eulette's slide mount and Clark would be the other most common.  Drilling and tapping the slide of course will be a requirement.
What kind of pistol are you putting this on?  What sights are on the gun now?  Those could play into what mount you get.

Rock River used to have 2 versions of their slide mount.  One was the standard depth / radius and typically covered the factory dovetail sight cut at the rear of the slide if you had a slide with a standard rear sight cut.   

They also had one that was slightly deeper and would fully cover the full low mount Bomar type sight cuts.  Not that it made any real difference, but it was more aesthetically pleasing since there was no visibility of the previous cuts on the slide. 

Not sure which one they are carrying now, I but only saw one version of 5 and 6 inch lengths on the website.

The second unit was called a "cover" rail. Originally made for the Springer RO but should also work for most low bomar mounts.

KC, it’s a Les Baer with the standard low Mount adjustable sights. I’ll attach a pic. I’m not too familiar with 1911s, but the curve on the top of the slide seems more pronounced than some. Anyway, I was hoping I could install a shorter version of the Mount as I would only need the rear most part. (Small, light dots) Is the concern stress on the mounting screws?

You can get a Rock River and cut it to match the rear of the ejection port,  this one has the slide rack ears. 1911 Slide Mount Options 51149a10I

I have a RO shorty rail that stops short of the rear sight and is clearance cut for the front sight. Requires drilling/tapping 3 holes. I also take standard rails and clearance for front sight and mill the bottom to clear the rear sight. It basically cantilevers over the rear sight. Rear sight elevation should be bottomed out. You count the clicks so if you remove the rail you can go back to your zero.
Here’s pic of shorty rail. I don’t have pic of the other rail.

Is their a channel in your Shorty Jon that allows the use of irons with the rib still on (and rings removed of course)?

Andrew,
Front is slotted for leaving front sight on slide.

Stress on the screws is only a small part of it.  With that sight mounting you would need a RRA cover rib to support the rear of the mount where there is less material from the sight cut.

EGW makes a plate that installs in the rear sight cut. Tighten the two screws to secure to the slide and mount the dot.
Have a Vortex Venom on my Sig and it does not move. An inexpensive way to go and no drilling out the slide.
