I'm a new member here but active on several other forums, including SigForum. I've been a Front Sight Bronze member for a little over a year and have have taken both handgun and rifle classes. They have all been first-rate. Most of everything you hear about Front Sight is at least partially true: classes are excellent, instructors are great, facilities are quite nice, it can get crowed on some weekends, they have a snake-oil marketing scheme, nobody pays list prices for a membership as shown on their website...... That said, I've been very happy with my Bronze membership and would buy it again in a heartbeat.
And yes, they do have specials from time to time. For example, I can upgrade my membership right now and transfer my existing Bronze membership to someone else, I just can't advertise it for sale in a public media. If anyone would like more info regarding my experiences with Front Sight, all of which have been positive, feel free to email me.
