dsk,
Haven't been to the WAC show in Puyallup for about six years but it sounds like it hasn't changed much.
I did some snooping at our new "Sportsmans' Warehouse" that just opened last week in Silverdale and all the high-volume Glocks (9mm, .40, and .45ACP) were present but no long-slide versions, no 10mm, no .357, and no G37. They have a pretty impressive ammo selection but no .45GAP. Prices were nothing to shout about . . . can do better at the local gun shops where I prefer to do business anyway.
I'm going to have to check out Bullseye Shooter's in Tacoma (the place were the DC "Sniper" got his AR/XM15!) and see what they have.
I don't want a G37, yet, but I just want to see one and shoot one just to say I did.
