OPENB Posted July 13, 2019 Share Posted July 13, 2019 Picked up a Legion today, and had a Romeo 1 sitting on the bench. The 6-48 screws that come with the Romeo are not the right thread pitch. I recall reading that the M17 mount holes are different. Does the Legion have different mount holes than the old X5, possibly the M17’s size? Anyone advise what screws I need to mount my Romeo?

George16 Posted July 13, 2019 Share Posted July 13, 2019 They’re M4 x .7 metric screws. It’s the same with the M17 since they’re also cut for the DPP. Link to comment Share on other sites More sharing options...
OPENB Posted July 13, 2019 Author Share Posted July 13, 2019 (edited) Thanks, forgot I was dealing with the ever-changing world of Sig. How long should they be? Edited July 13, 2019 by OPENB Link to comment Share on other sites More sharing options...
ELSOS Posted July 14, 2019 Share Posted July 14, 2019 So you’re saying a Romeo 1 can’t be mounted to a Legion? Link to comment Share on other sites More sharing options...
OPENB Posted July 14, 2019 Author Share Posted July 14, 2019 Not without great difficulty it appears. The 6-48 screws that come with it are under sized for the tapped holes in the slide. I picked up some M4x.7 screws tonight from Home Depot, and I can’t get them started in the holes either. They are too big & not threaded the same as the holes. And they are too big to fit through the holes in the Romeo 1. Not really sure what’s going on. Link to comment Share on other sites More sharing options...
ELSOS Posted July 14, 2019 Share Posted July 14, 2019 From what I’m hearing you can’t mount the old Romeo 1s without an adapter plate. Looks like the new Romeo 1 Pro and DPPs will mount directly. Link to comment Share on other sites More sharing options...
OPENB Posted July 14, 2019 Author Share Posted July 14, 2019 Mounted my Deltapoint Pro 7.5 on my Legion slide today. The stock M4x.7 screws work perfectly & snugged down perfectly. Appears this is the only practical choice in dots for this gun at this time. With the sight mounted & a 21rd. mag with Springer base pad & Grams guts, it weighs 43oz.

George16 Posted July 15, 2019 Share Posted July 15, 2019 To mount the old Romeo 1 on the X5 Legion, enlarge the mounting holes on the Romeo 1 using a 4mm drill bit on a drill press. The aluminum housing is pretty soft. That’s what I did when I mounted a Romeo 1 to a friend’s M17 which shares the same cut with the X5 Legion.

Akkid17 Posted July 17, 2019 Share Posted July 17, 2019 Has anyone contacted sig to see if they have a solution? Or is this just getting pushed onto the consumer again? Link to comment Share on other sites More sharing options...
