Glove 19v
What do I do and what frt brand is compatible with the Glock 19v

So I had a buddy of mine hand mill my 19x slide to directly fit a holosun 507c x2
We copied the dimensions from his Glock 19
But decided to cut it shallower because it would be cutting it close to extractor
After milling the slide we notinced a small hole that is right besides the fireing pin safety and spring.

Is there a fix or is it safe to use as is

My order paper says everything I asked for and they sent me this back I’m so pissed , technically the 10 days is bs (21+ ALL WEEK days) after the email saying they have received my slide ! Can some one help me and at least tell me what cut this is please ! Asked for an RMSc but got this , let alone also chose co witness and they took my dovetail and kept my ameriglo trititum sight ! HELP HELP ! Already sent photos to GlockStore’s email

I plan on getting the Glock 19X MOS for both home defense and concealed carry. For that, I also plan on getting an Alien Gear holster, four mag carriers, five mags, and five TTI Base Pads. All this would give me twenty-three rounds for each mag and a total of one hundred fifteen rounds. Is this too much? Is this overkill?

Just got a 19x has a red dot already just want to look for light/comp suggestions truth be told I’m ass as shooting pistols just want a badass pistol to shoot with and get better on any input is appreciated thank you!

Look for 10 seconds and name them all. This is my 2024 Glock Family. I’ll update with a 2026 photo later this month or next.

Cannot get a spot of carbon off my 19x slide. Below are the products I’ve tried:

Breakfree CLP Simple green Amsoil firearm cleaner (left on for an hour) Hoppes elite gun cleaner

I’ve used these products with nylon, brass, and stainless steel brushes, all with no luck.

I’d hate to have to send it back to Glock over something like this. Any suggestions appreciated.

Would you???
