I should have it by the end of the week.

I had asked in a thread previously about a plate to mount a Delta Point Pro (I didn't get any responses), now realizing the DPP is too big.  I already have a DPP, so that's why I asked.

Is there a good paddle holster for it?  Leather of Kydex?

I don't want a Holosun if I mount an optic on it.  I don't know anything about optics on a handgun.  What are my Made in USA options?  Do I need to purchase a plate for mounting?

Best place to order extra mags?

Anything else I should know?

Check on Gun.Deals for mags. Pricing is all over the place when you add shipping. I can't help on the dots/plates but PSA has 5.7 Fiocchi fmj ammo in 150 packs for $70 plus shipping, which is about the cheapest, if you can call it that,  I have found for plinking ammo. I missed out on the end of year ammo deals. Hopefully more will come soon.
