I took my first class in May of this year. It was solid training, and I'd particularly recommend it for someone who has never taken a class, hasn't had any training in a while, or has never touched a firearm. I have mentioned before that if I were going to send my wife somewhere, Front Sight would be it. If you're a Seal, experienced SWAT team member, or someone else who has a ton of experience, I'd suggest going to see about their teaching techniques rather than hoping they'll shrink your 2" groups at 25 yards. They really have it down to an art.
I have NO idea what Piscator is talking about regarding safety and in doing all my research, never saw a similar complaint. The closest I ever discovered was one of their old instructors, who is running his own school, mentions that the method of chamber check he used to teach (and I believe Front Sight uses...hard to tell from his description) has some problems, but he didn't elaborate on what his new method was. They're also up front and all incidents are available on their site...and it's not bad considering the sheer number of students they go through. I saw that other schools have accidental shootings, but tend not to mention them, so comparing numbers is difficult.
The biggest thing about going is probably attitude. If you go in looking to dislike it (which a lot of people seem to do), you'll find things to pick on...whether its their stance, grip, or some other item...never mind that they're not jamming it down your throat as The Way, they just ask you to try it and a lot report that they end up liking it. If you have a good open attitude, you'll probably have a great time. One police instructor (who was amazing to watch shoot) in my class probably could have given the instructors pointers, but he still had a great time and great attitude in the class.
Other complaints seem to be that they'll try to indoctrinate you to Scientology, or repeatedly try to sell you memberships. The only mention of religion was a pair of Born Again Christians I happened to sit near during lunch, and the 'hard sell' is a video playing during a lunch which you're free to ignore, or not even be there (although it is the most comfortable air conditioned room around).
Recall that the 4 day handgun course they teach is most of what you'll ever see reviewed...sort of their bread and butter course, and it's very regimented to getting shooters up to speed safely...try to muck with that, and you'll probably not get a very warm welcome. They do offer more advanced courses, but I've seen very little about them as the number of classes and attendees is comparatively low. Personally, I learned a lot, but would have liked a little more attention...I think I was too 'good' compared to the beginners so didn't get the 1 on 1 help that would have sped up improvements to my grip and trigger control, but I DID learned what I needed to by the end of the class, just not in the first day or so that the individual attention would have accomplished.
As for cost, it's very easy to find certificates to go for MUCH less than the listed price...I don't think anyone ever pays list price. My grand total for the trip, not counting ammunition and gear, came to around $200 a day for the 4 day class...that includes gas to drive about 900+ miles each way, stay in hotels, eating out every night, ordering food to the school each day, certificate, and 'background check'...so combining with a friend would drop the per day cost quite a bit.
The course also did change in the past year, so older reviews may be a little off. No more night shoot (that was deemed too difficult to run safely given the increasing number of new shooters in the course), and no more turning targets (supposedly to make it less stressful, but I'm thinking the cost of building turners into all the new ranges they've build was getting expensive). There were a LOT of people in my class who chose not to even attempt the graduation test, so maybe there is something to the turning targets not being all that necessary or desired by an increasing number of their students.
