Here's what I ended up getting for my new EDC:
- Walther PDP Full Size with a 5-inch slide + four 18-round mags
- Holosun 507C with 2 MOA red dot + a 32 MOA ring reticle
- Crossbreed Founder's series IWB holster
I'm searching for a good leather OWB holster with snap loops for easy on-off of the belt, similar to the holsters that RD Warren used to make (see photo below) - but I've not found that just yet.
Thanks to everyone for the suggestions and comments. Y'all helped a lot!
