Springfield Hellcat OSP: Removing the Slide Lugs and Mounting the Holosun 507K

The Springfield Hellcat OSP has 4 lugs under the plate. The Holosun 507K does not fit natively. In order for the Holosun 507K to fit the side has to be modified. Specifically, the 2 rear lugs need to be milled flush and the 2 front lugs need to be reduced. Holosun is releasing an “upgraded” version of the 507K in September (likely due to the Trijicon lawsuit). As of the date of this video Holosun has not released a complete list of the changes only that they are “relocating the buttons” and that the “footprint will not be changing due to the fact that the 507K is waterproof.”
I’m not a milling expert, machinist, gunsmith, etc … just your typical “hands-on” type guy. I’m not opposed to paying for work when required (or feeling lazy), but do generally at least consider DIY. The gunsmith at my LGS told me he’d do the job for $50. I already own a Dremel and some bits, so there wasn’t any investment on my part, so I chose the DIY route. Start to finish it’s about a 20-30 min job. It took me a good hour because I forgot to retape the screw holes and therefore had to disassemble and clean.
Tools Used:
1. Dremel
2. Dremel bit #9903
3. Dremel bit #83702
4. Metal file
5. T 10x4 screwdriver
I ran the #9903 bit on speed 1; Dremel bit #83702 on speed 2.
I’m happy with the outcome, really like the 507K and Holosun’s in general. I have Holosun’s on some rifles and other pistols, so so standardizing as much as possible is important to me. This is why I didn’t go with another brand.

[@ColeDedhand]

After watching a bunch of reviews of the shield optic, the romeo zero, the hex wasp, the RMRcc, and the HS507k I see the clear winner is the HS507k. If I have to modify my gun to work with the best optic then so be it.

[@stephenboldrey9973]

If your putting the plate on under the optic why mill anything out . The plate correct’s everything . If you want the sight to cowitness. Better just get the replacement sights for the suppressor height sights . No hacking up your gun is required that way

[@jonmichael1974]

If you're using a plate you don't need to mill the lugs, nor should you. However, your optic will sit higher because of the plate. Therefore your factory irons will not cowitness. With the flush mount and the 507k I have roughly a lower 1/3 cowitness. So with a plate, you won't have backup irons or you'll be buying taller ones (NightFision is a great option).

[@TheJpo911]

Hows the rear sight? Can u still get a low cowitness with the rear sights?

So I got the rear lugs flush, left the front ones alone because if I hold the optic on the slide, there is 0% light coming through. However, once I torque down the screws, there is the tiniest bit of light coming through - maybe the height of a piece of paper. If I back the screws out, the front is again perfectly flush. Is this gap anything to worry about?

@Jason Sinatra All blemishes are 100% covered up by the optic. If I chose to remove the optic the OSP plate would also cover them completely. Springfield professionals have already adapted the slide with the OSP model. I just undid 1% of their work to accommodate the 507K.

[@brucecook502]

This is an uneducated opinion here, I am for the first time here soon going to put an optic on one of my handguns and I have been doing lots of research on optics, optic plates, and all sorts of related stuff and my question is, instead of grinding those posts off the slide, couldn't it be possible to just drill holes deep enough on the underside of the optic itself so you could take advantage of all four mounting posts on the slide? Like I said, my suggestion is an uneducated opinion because I have never had an optic before, but I just thought it would make more sense to do the modification on your optic rather than your more expensive gun itself, or would it cause damage to the optic? I would have guess if the bottom of the optic is thick enough to have holes on the front, wouldn't it be thick enough to do the same on the back so you don't have to modify your slide?

[@jonmichael1974]

I asked Holosun this question. Their response was two-fold: 1. It will break the waterproof seal. 2. They cannot tell you where any electronics are located and would therefore in all likelihood break the optic.

There are many optics that fit without modifying, Vortex defender CCW is a great option, roughly $200 USD, direct mounts with no adapter, has full co-witness. Some other options are shield rmsc, and crimson trace 1550, but I think the vortex is better of these options. I like Holosun, its a bummer they use a "modified" footprint that ALMOST fits, I would prefer a 507k ACSS vulcan but I prefer direct mount without modifying, so the Vortex CCW is the best option I found.

Comments in all caps and run-on "sentences" make me cringe.

​@@jonmichael1974And what he doesn't understand is... Those lugs are REAL close to the slide, and the bit would mar the slide if held horizontally. Great job bro! I did the same thing to my Shield Plus. I wasn't sure if it would rust, so I just dabbed a little black Rust-Oleum on the bare metal. Thanks for sharing. Liked and subbed.👍 Be safe!✌️

😂 OR buy a plate from C&H 🤷‍♂️

[@jonmichael1974]

OR ... check the date this was posted. No plates existed at the time. :-) Further, any plate will reduce the cowitness % so it's still a great option. As of today, I'd either still take the same approach or hold out for a Holosun SCS direct fit.
