FS,
Good for you for going to get some training!
I have no problem recommending brands:
Take a loot at Blade-Tech and Blackhawk.... Personally, those are the two holsters I use most often. I like the BH SERPA for OWB and I have used several BT OWB that were great and I prefer their IWB offerings.
If you are looking for a training holster on more of a budget, G-Code makes some great options as well.
After you train, post a report!
