I believe they used to. 1911 is tough, better/more durable optics require adapter plates. Looks like Primary just wants to concentrate on few brands. 1911 not being offered does not surprise me but absence of SIG does.
Which makes them totally useless for me.
I don’t think the reason they are back is because they witness shoddy work elsewhere either.
They are back because their employees unemployment has run out and they burned through their stimulus money. 🤬
They always had the best turnaround on a quality milling work. I didn't like their cerakote, and that's the only knock that I have on them. When I used them, I specified the nitride treatment on my slides.
