You pay $6,000 for a rifle and $3,500 for an FFP optic with mil radian turrets, buy 14 different shaped bags to use on all the different props, pay $250 match fees, learn to twist your body like a pretzel, get an "I'm a sniper" attitude, argue about everything, cheat whenever you can and buy a backpack big enough to carry a house inside. Oh, most importantly, you beg for sponsorship from anyone/every company even remotely connected or interested in the game. Did I mention that you have to buy those "PRS Pants" that are $300 per pair?
But, seriously, I've helped some friends put on PRS matches but never shot one. Would I? Hell yes! But only if I were 43 instead of 63. I spent about 25 years blasting away at USPSA targets in both pistol and three-gun matches and there is no doubt I love the sport but I decided I was just done with all the "running & gunning". You, as stated already, need not only classes to build your skill but a true mentor to help you buy the right equipment the first time and help you get through the demands of the PRS shooting world. Also, you must be aware that PRS is a "profit" sport for the trainers and match directors. They will, unfortunately, try to sell you on gear just because they are getting their cut.
If it seems I am being critical (and maybe so) of the game it doesn't diminish the fact that PRS has done rifle shooting in general a great deed by getting thousands more shooters behind the rifle than any other of the rifle sports. That is indeed a good thing.
