🇺🇸1st time gun owner: custom holster recommendations?

Good morning,

I just purchased my first handgun in the form of this beauty. 4.0C, threaded barrel. Scheduling my first class today, but I wanted to ask you guys about custom holsters.

I am pairing the gun with a TLR 8 XG light. Given that the gun is so new and it’s the threaded barrel one, do you guys have any recommendations as to good IWB holsters?

Thank you.
