This is halfway right, but they still screwed up by removing the rear sight notch. TSD is the only place I've seen that really does the red dot installation right, IMO. One Source Tactical sells TSD slides, and TSD slide modifications on Glock slides: http://www.onesourcetactical.com/ad...l.com/advancedcombatglockslidemodificationsoncustomersslide-1.aspx#.T2ftA9Xa9-w

I'm not associated with them in any way, but it's obvious there's a big advantage in dot aquisition when you still have useable iron sights too. Of course, it costs more money to do it "right".

TSD does a quality mount. I have a Lone Wolf slide for my G21 that they did this on back when they were sourcing their slides from Lone Wolf. Had some problems with the slide itself, but their work was quality. Shouldn't be a problem if you use the G20 slide.

Lone Wolf will also do a "slide melt" mount that is similar.

I've put ~ 1000 rounds through mine - granted .45 not 10mm, but no shift in zero and I have to say I wish I'd done it sooner. I find target acquisition to be much faster, and I'm more accurate with it too.

When I was shopping around for a company that could mill my Glock OEM slide, I learned the Slide Melt service from LWD is unavailable for OEM slides. I believe that is still true (see statement on their web site currently).

There is another important distinction in the quality of craftsmanship that Mark Housel or TSD/OST provide. The last time I checked, the LWD Slide Melt makes the slide cuts straight across, whereas Mark Housel and TSD/OST carefully curve the forward cut to exactly match the contour of the RMR base.

You are absolutely correct - that is why I said similar not the same. LWD won't do OEM slides, and I think the fit from TSD/OST is much better. (It's so good you would think it was factory direct...) Now that I got the slide working, I'm happy with the product.
