I’ve seen a lot of SureFire products as prizes at matches for the last two years, but I’m not sure if they’re coming from SureFire or vendors. I suspect that SureFire has been generous to USPSA in some way, because of the illogical ruling made on (sound) supressors by the USPSA board of directors last year.
Blade-Tech was very generous last year with their injection molded Kydex gear.
In addition to those you’ve listed, we’ve had prizes donated by the following locally:
Cor-Bon
Montana Gold Bullet
Zero Ammunition
Hogue
Robar
We had a few others who promised prizes (even to the point of telling us when the stuff shipped), but we received nothing.
