I can’t speak to this particular class or this particular instructor as I’ve never trained with this instructor…
I can, however, speak more to the point of training in general. Believe it or not the sentiment you expressed is quite common. Just a few months ago on another site someone asked me if they should spend X dollars on a new railed Sig P220 or the same X dollars on the tuition for a training course. “The class is 3 days, but the Sig would be something I could have forever!”
This is the question I asked him:
If you knew that in two weeks you’d be involved in a gunfight, what would you rather do in preparation: Buy a new gun/more ammo/etc or get training from a competent professional?
Formal training is certainly expensive…Lord knows I’ve dropped a lot of money on it over the years. With ammo prices these days it’s worse than ever. Still, I’ve never regretted a penny of what I’ve spent on training and I’m constantly on the lookout to do more of it.
In formal training you learn everything you’ve been doing wrong without even knowing it. You learn lessons about mindset that can quite literally save your life. It’s one of those figuring out that the Earth is round sorts of things. Everyone I know who has taken formal training has always signed up for more after their first class…and to a man they extol the virtue of participation in formal training. That’s what I would call a “clue”.
Having guns and ammo is great…but knowing how to use them is dramatically more important than buying more guns and ammo. (…and sadly much of what passes for police and LE training is inferior to what you can learn from competent instructors like Larry Vickers, Ken Hackathorn, and others, so even that training is often not good enough) Most people (myself included) are not capable of teaching themselves how to fight with a firearm any more than they are able to teach themselves calculus.
My first training course was a handgun course at US Training Center. (Formerly Blackwater USA) I went into the first day thinking I knew how to shoot. By the end of day 2 my illusions of adequacy were shattered and I came to the understanding that I had just opened the door to a whole new world of information and skill that I had no clue existed prior to that moment. When I drove away from Moyock I was a 100% better shooter than I was when I first drove down Puddin’ Ridge Road.
When it was over I had the irresistible urge to go back in time and kick my own ass for not signing up for classes sooner.
My advice would be this:
Take the class. Then when it’s over honestly assess your experience. Training (especially the first formal training session you attend) won’t always be “fun”. As a matter of fact, it can be downright humbling. Assume your ego will take a pounding and put that aside. Show up to the class with a positive attitude, safe gunhandling skills (something else formal training teaches very well) and the commitment to listen 10 times as much as you talk, and odds are that you’ll learn a bunch and you may even start to have a good time.
