Drill and tap jig

[Joe4d]

considering drilling and tapping a standard dust cover 1911 for a Cmore, or maybe some other mount. I do have a drill press, but anyone know of a source for a Jig so I can get it near perfect ? I see them for a couple other guns but not the 1911, which is kinda odd as way more of them running optics than CZ or Witness

Problem is there's two ways to get the 1-degree angle to the scope so it matches the 1911 barrel-- put the mount holes at an angle to the scope base, or put the holes in the frame at the angle and leave the mount square.  You don't want to do both or neither, so it depends what mount(s) you want to use where you drill. 

 

Then there's a bunch of different hole patterns.   Most are .375" on center, but not all, so again depends on the mount...
