Turns out I like shooting the thing, but I have a hell of a time aiming with open sights (on anything...not just this gun). I need to find a way to get a reflex sight mounted. The 21mm width is there but 9mm is a LONG way down into the slide to cut a full rail.

Alternatively I can mill the top flat and drill/tap the slide to mount a rail like the guy on youtube, but it's a long way from my preference.

If you remove the rear sight you'll be left with a couple screw holes and matching screws. Use your imagination. Others have.

I would prefer have a milled mount over using screws. If I use screws then obviously there's already options immediately available. I want the mount cut into the slide. That's why I asked if that had been done before versus "how could I mount an optic".

Then "No". I don't believe anyone has attempted it. Let us know how it goes.

Obviously I would share the results...but I'm not really willing to cut blindly into the slilde.

Has anyone cut or broken (and posted about it) a slide in a way that would let me see how much material I'm dealing with?

If someone here has, they'll reply. Another option is to invest a few bucks and get another slide on one of the auction sites and just play away with it.

I'm working on that, Adam. I'm actually trying to find a damaged one if at all possible, though...I want to cut it into slices so I can really know the material. They're cheap enough that it's not a big deal to cut a good one up, but with such things my preference is to start with a piece that is already defective.

Looking at some of the other cut jobs some people have made (like this one) makes it look like the back half of the slide is virtually solid material.

I believe it's mostly solid Zamak.

Another interesting option would be to cut the slide back from the muzzle, and mount a red dot optic directly to the bbl.

So it could be neater, but it's the best a harbor freight drill press, a 1/2" end mill, a v-groove router bit, and a hardbor freight 2-axis vise can really do.





The ends need to be neater but I don't know how to clean them up with what I've got. I'm also trying to keep the screw holes intact for the rear sight (just in case) so I'm not gutting the groove until I have the sight in hand and am ready to mount it.

Not sure I would have gone that route. Full width square cut just shy of bottoming out on the rear sight pocket, cut a length of pic rail to fit, drill the rail and slide, tap the slide, mount the rail, and use a mini rds.

That was an option, and I had nearly 1/2" of material to tap into, but I don't like screws...especially considering how soft this material is.

BUT I'll probably end up doing much the same with the other gun...maybe I'll mount a rail as you describe and see how it holds up. I've just had poor luck with screws in the past.

You could have helicoiled it.

Edit: I have the same drill mill setup.

Does the weight of the optic come relatively close to the weight of the material you removed? If it's not, will the gun cycle correctly?

I don't think so. Holding both guns I think the factory one is noticeably heavier, though not considerably. I ran 80 rounds through it today, and 20 through the unmodified one, and I was quite a bit more accurate with it and had no feed/fire issues. On the contrary, the factory gun had multiple FTF/battery issues. Coincidental I'm certain.

That test would only have merit if you used the same magazine in both guns. Most C-9 feed issues are mag related.
