I've been to TWO in St Louis. Both a great time!
Take you kids in scout uniforms, and they get in free! Every gun (no matter how expensive) has the firing pin removed. The guy who owns Kirkwood Outfitters is a big wheel in MO NRA. He was telling me that one of the ultra high-end mfg's didn't want to comply until they old them to get out.
Anyway, my boys and I had a blast fondling all the cool wares. You can pick up and handle and dry-fire to your heart's content. I actually used it as a learning experience. I told my boys they could pick up and touch whatever they want, but they had to 'clear' it first thing, every time...even if their brother hands it to them, and they saw him clear it. Gave them lots of experience on how to open and check every type of action out there!
Words of warning...you will leave there wanting LOTS of new stuff...and when your wife sees the wet spot on the front of your britches, she's going to assume you went to the East Side!!
Can't wait!!!
