SIG ROMEO X

[Noah]

Ja. I did the QRC for this new optic last night, and noticed Sig spent quite a bit of time on the fasteners in re: loctite 243 (blue). And the torque value specified is 18 in lbs, which is a bit more than you see for Holosun's K series (15) say.

So I gather the Fuse is the only pistol that this new LOC optic currently mounts on? So a regular RMSc optic footprint is a no go? Interesting move by Sig.

Their video said future 365s would be moving to the same cut as the Fuse.

The Fuse still direct mounts the other RMSC adjacent optics, yes?

This just makes me want a Fuse with a manual safety that much more.

If sig eliminates the ability to mount the K series optics to the 365 line they will shoot themselves in the foot pretty hard. I’m thinking about a Fuse, but if I can’t recycle my EPS Carry, I’ll have to save up for another optic that I won’t be able to use anywhere else. So basically I’ll pass and go elsewhere. This IMO would be stupid, but maybe they think they have enough critical mass to become a driver in the optic footprint debates vs a follower.

Not a fan of the underside screws. Even though when I degrease, apply loctite and torque properly, I’ve not had any optic screws walk loose, I’m still not a fan. I like quickly seeing witnesses marks when I look over my gun. Even if they don’t fall out, I can’t imagine screw heads dragging on the FCU being helpful for reliability.

Can’t you still mount a Holosun direct on a Fuse? I think it is still backwards compatible.

That’s my impression, too.

Makes my ears perk up, too.

Anyone here with a Fuse that can check for the forward cut and mounting holes shown in the video? I’m curious if they all have them.

Now I’m wondering if it’s possible to mill an existing P365 cut to take the forward tab and through holes needed for this sight. It sounds like something CHWPS would be able to do, and would be cheaper/easier than getting a new slide for my XL upper. I’m gonna ask.

I wouldn’t bet against that!

I’m sure Sig will sell a new slide kit for $600 too

IIRC a guy over in Gen Pop had issues direct mounting a 507k on his fuse. Something to do with Holosun not fully complying with RMSc in terms of the depths of the fwd recoil bosses. I’ll go dig out some more details.

There were conflicting reports of the same in the Fuse thread
