Problem seating RMSc on Hellcat OSP

Hi All,
Has anyone who's tried the Shield RMSc run into this issue? The sight won't sit flush on the recoil lugs on my Hellcat OSP. I've tried a Swampfox in the past and it fit just fine, but this RMSc won't. This picture shows the best I could manage. This is without the screws, it's just sitting on the slide.

I'm waiting on a replacement sight so hopefully this one's just out of spec. But while I'm waiting I thought I'd ask just in case I'm clueless and doing something wrong.

Mine was tight and took a slight forward tilt, some slight wiggling, and a little pressure to fully seat. It snapped in securely after a few seconds. I was careful not to apply excessive pressure. As you stated, it might be out of spec. If that fails, you might try a tiny drop of oil applied with a cleaning patch on the lugs. If it snaps in, remove it and thoroughly clean the lugs and the holes in the sight with Q-Tips and alcohol then dry completely and reinstall. Torque to 15 inch lbs. After 4 months, no problems! I chose the polymer RMSc after an email to Shield as it is less likely to crack than glass according to them and has a hard coating over the polymer. I bought a LensPen Law Enforcement Kit to keep it sparkling clean without scratching in seconds. Here's a link: https://lenspen.com/product/lenspen-outdoor-pro-kit-for-law-enforcement/

Do the holes and posts actually line up? If they do, it might just be a little extra coating on either the sight or on the pistol. Like Lock n' Load said, it may just be a really tight fit and a little lube may be enough to get it on. Or maybe take a scotch pad and smooth out the posts and the holes. Not sure I'd use sandpaper unless it's a REALLY fine grade, but sounds to me like it just may be a thick coating issue...

I can't speak to the RMSc, but I do have the SMSc on my HellCat and with no issues. It fit right down onto the pins and bottomed out as it should. As Lock n' Load said ..... 15"lbs and a tiny dab of blue "Locktite".

I would imagine the SMSc may be more consistent with tolerances. It’s polymer with no coating. The RMSc is aluminum and has a coating (paint or some such coating) and a little extra coating may make it just thick enough to have a hard time going on. Just speculating here. :)
 
Helpful tricks?
If still have issues with sight mating on gun, try pencil & paper "rubbing" on both slide & sight to see which impression is off & by how much. - Number 2 or another soft lead pencil works best. (Place paper or surface checking then lightly rub with pencil.)

Measure raised rubbings, compare surfaces. Will at least tell you how much's off where so know which direction to direction to go or if can. Is "low tech" method but pretty effective. Another is an aluminum foil method that can work too. Place flat foil on surfaces to be transposed, gently press down to expose raised or recessed areas. Result is about same procedure/method/result except can use another tool to press down foil to transpose surfaces. Hope that helps get your sight on. Usually works better than getting a bigger hammer?

I tried that but no go. I tried every cant option there is and no luck.

I returned the sight and I'm waiting for the replacement to arrive. Hopefully I'll have better luck with the 2nd one.

I'm having the same issue.. Did you get the replacement and if so how did it go?

Experiencing the same problem with my SMSc which I just received this morning - monkeying around trying to get it flush.

EvilElmo- Forgot to add that I used a tiny drop of blue Loctite #242 to the screws on the final install to keep them from backing out due to recoil. Also got the Dream Plastics neoprene cover (2 in package) for storage to protect the sight and lengthen battery life. It fits perfectly.

I had the same thing but did manage to push it down hard until it was flush.

So about that Loctite... If a single spec of it is on the bottom of that right screw it will drip into the ejector spring and your gun is finito. If that is even possibly the case I would take the whole thing apart real fast and remove the ejector/spring and rod and flush that out before it dries. Hopefully this is all necessary for you but my bro proved this to me and now I tell everyone.

I noticed the spring on right side, definitely wouldn’t want to put the wrong screw length in there, interesting about possible loctite debris dropping there.

Actually since I wrote that I've changed my method slightly. I never have liked any locktite on my guns and very rarely ever used it, but with the SMSc being new to the scene, and it also being so new to me, and the screws being so tiny, and the holes being so small, I decided to try it. But ... as I wrote "a tiny dab" of locktite. I can't be more emphatic about that 'TINY DAB'! However, the first time I replaced the battery (having to remove the screws), I gave it much thought (btw, had no issue removing screws with that 'tiny dab') and decided to go back to the old days of mounting regular scopes on my high powered rifles and just used a 'tiny dab' of the same white paint I used to make the 'witness marks' on the screw heads and sight base. I used a wooden toothpick and dip it into some white model paint, then dab it on the screw head with a matching mark on the base of the sight. Actually I simply touch the toothpick to the line between the screw and the mount ... one touch makes both marks. Either mark is barely the size of a straight pin, but will tell you at a glance if either screw has loosened even a 'smidge'. I use the same toothpick and paint to apply a little dab on the bottom 2-3 threads on the mounting screws after a good cleaning with a Q-tip and some alcohol of both the screws and the screw holes. In all my years of mounting regular scopes on rifles, and even sme early model "Aimpoints" red dot scopes using the 'white paint' method I never had one loosen. And never worried about not being able to remove a screw with locktite on it. Now let me say this: All Locktite flavors serve a purpose when used according to instructions and in appropriate places. It's a very good product in it's place. I just won't use it to mount any sight to my guns.

A "tiny dab" (again emphasizing 'tiny dab') is hardly enough to drip down onto anything I believe, but if I were concerned about it dripping, I'd simply take the slide off the gun and turn it upside down on a flat surface till the 'Locktite' set up. (y)(y)
