Suggestions of smith to mill rear of 9mm 1911 to receive red-dot sight

Post by Mac2 on 5/9/2018, 8:18 am

Have used a rear sight insert that has red-dot receiving holes on a Range Officer and on Colt 9mm.  The dot ends up higher than desired and spoils whatever natural pointing exists with 9mm 1911.  Range Officer proved also to be too heavy and Colt LW Commander has a distracting rattle even after tight bushing and improved trigger.  Ruger 6722 that I have tried are more tight than Colt, but still not tight enough for bullseye.   Found a new-old-stock (NOS) 1911 that is tight where it should be but with strange radioactive night sights.  First tests with ball ammo (and using the strange sight) gave good groups at 25 yards (but some 5 inches high) - so the pistol has promise for use in bullseye (with red-dot sight).  
A few ways exist to mount red-dot sight on a 1911 and they have been considered.  Prefer slide mount - as low as possible.

Please share experiences with smiths who are able to mill the rear of a 9mm 1911 so as to low-mount a Venom red-dot sight.  [Perhaps not the best sight outdoors, but most competitions are indoors and the Venom is light and easy to use]  Thanks

The rear of slide can be easily milled flat with 1 degree offset and an aluminum Weaver base screwed directly to the slide for the Venom to mount to. The depth of slide milling cut can be minor or deeper depending on how much weight you want removed from slide. The aluminum rail can be machined to compensate for that depth. I do several of these a year. Not a big deal. The Venom is similar to Burris FastFire, I have a friend with many of them on his pistols and he’s pretty happy.

Thanks Jon.  The Burris FastFire 3 has been found to be difficult to operate.  It was the first of the small red-dot sights used.  As you noted, the Venom fits in the same holes.  One of the most desirable attributes of the Venom is its ease of being turned off.  
Have a Glock 34 that has a cut for red-dot sight - use it once a year for a Glock match.  A few other pistols have the same cut from the factory.  All seem to have, and to involve, a set of intermediary plates to adapt for different hole patterns.  The Venom comes with the ability to mount to such a plate (and be short) or alternatively to mount to an included adapter that attaches to a Picatinny rail, which ends up with the dot being higher than is the case with the first scheme.
I understand that you mount a Weaver rail ( somewhat like a Picatinny STD1913 rail) rather than use an intermediary plate.  Pictures?  Web site?
