I bought these years ago and again last year, so I knew what I was getting into.
these work fine with an aftermarket magazine but not a Glock magazine.

The problem is Glock's butt plat on the magazine is thicker then aftermarket stuff, which keeps them from going up far enough to catch. To solve this problem, you have to change the angle to allow for the magazine to go up far enough to catch.
Here is what I did.
first, I used a carbide burr to ruff out stock.

then diamond burr

finish shaping with 600 grit sandpaper drum 1/4 inch

Now it is time for the polishing part of the fix.
I like to use there 3m buffer wheels

I like those rubber wheels too. they will give you a higher polish (shinny look) but if you plan on sandblasting them it is a wasted step. I plan on blasting them so there ready of blasting and paint.

You can see the difference

AFTER:

I like to take a hand full of Glock magazines and test as I go to make sure I can keep a tight fit without any wobble.
When I can run five mags in and out that fit tight It's right on. Aftermarket magazine may be loosie goosey But hey!! you should be using Glock mags, they just work all the time.
If anyone has any questions on mod stuff just ask, I've been doing this stuff far a long time.

Nice work, when it comes to doing mods on frames, I can make just about anything work or at least give it a try.

When I first started, I was so nervus about hacking into stuff just because of being afraid of screwing something up but sometimes you just have to go for it. The more you do the more you will build up your confidence. Finally went back and modified the Syndicate magwell similar to what you did above. It came out really nice being as it's also poly, it was easy to shape and blend then match going through the grits to 3000. Now all mags fit.

As a side note, I picked up a Syndicate poly magwell for P80's at Brownells. Really nice fit, but it won't take Glock mags! It takes the P80 and Magpul mags, but not the OEM. Go figger. Thinking about modifying my Glock mags - putting a slight angle on the baseplate, but I'm hesitant to do that since if I grab a mag that hasn't been modified, I could be screwed.

Just change the angle like I do, it's not a problem for me I will mold them into the frame and repaint. A over a year ago, I paid $15 each a few months ago I paid $30. I still think I saved some bucks. A good aluminum magwell will run $80 and higher.

I've got the same magwells. I hate em. Took them all off. They don't take magpul's either. Work fine with the P80 mags tho.
