The gun show is a great place to go to be able to fondle most any new gun you may have an interest in. Most gun shops carry a limited inventory and may not have several I'm interested in examining. Same with the used guns.
I've found some pretty good deals on guns and ammo. I've found a few holsters and mags along the way too. The holy grail of mags for me is the Walther TPH .22, and POW, there it is...setting in a display case of some obscure gun guy...waiting, just for me, and at a price I'll pay! Made my day.
My last show provided a FN 5.7 pistol for $700. That's a good price. I found ammo for it for $15/box. That's a
very good price. You never know what you'll find.
You only need prepare yourself to have a good time, enjoy the sights and scenery and go with a good attitude. Do not expect to find Hitler's PPK for $235. Ain't gonna happen. But maybe you'll find something like a S&W K22 in perfect shape for $350. Ahhhh, that's the excitement!
It was at a gun show that I was first able to fondle a HK P7. Thank you God! Use the show to increase your knowedge, find an occational trophy and just enjoy the day. Have fun.
