Unfortunately I think your pickings are pretty slim on the western slope. It may be worth your while to come down to Denver for a 2-day weekend class- many of which are offered by Meanstreets Tactical and Defensive Response Training. I have taken many classes thru DRT, they sponsor Andy Stanford during the summers as their stud guest trainer. Look up his bona fides on the internet. I recently took my first class from Meanstreets, they seem to have it together, but I have not as of yet taken a pistol class from them.
