You would think that a 400 hundred dollar sight would come with a mounting plate for sigs. Nope.

Plus the have a page for mounting instructions and when you go to that page it is specs for the sight and no instruction. Am i supposed to use loctite? is there a required torque?

I wish I had went with trijicon

My manual, on page 9, says the torque is 28-30 in-lbs for the mounting fasteners.

Does Trijicon now come with a plate? Hell, Trijicon doesn’t even come with the correct screws, or a dealer plate.

I thought current production guns were already milled for this optic.

If it was advertised as coming with a specific mounting plate for a specific firearm
then I would be pissed. ...............................................drill sgt.

Apparently I didnt read the list close enough.

- M17
- P320-M17
- P320 XFive Legion
- P320 XCompact
- P320 XFull
- All PRO-CUT Slides
- P320 Pro Series

It works on all these but no the Xcarry

I am going to contact sig customer service and give them the serial number and find out what will fit.

the gun shop employee ordered a p series conversion plate and said "i'll make it work!" uh no you won't.

talked to Sig CS and they verified that my 320 carry will only mount the original romeo1. Luckily they had a refurb available or who knows when I would have got one!!
