I spent most of today, wandering from gun shop to gun shop in Boise, Idaho today (and a few adjacent communities). I was looking for the hex socket to change the front sight on my Gen 3 G23 and a bud's Gen 3 G22. I was doing this because the one I had has magically disappeared into the block hole that surrounds my work bench. I was in nine (9) different shops and totally surprised about some of the reactions to my request. (These are well established shops with knowledgeable operators, not Walmart, K-mart, etc.) 1st shop: "Oh sure. I have one but you can't buy it. It's only for dealer use. 2nd shop: "Ya mean this one? (He's holding the drifting vice for the rear sight). 3rd shop: "Well, two of us are Glock armorers and WE have them, of course. I can order one for you. Runs about $28.95 + tax" 4th-6th shops: "Sorry, we send our repairs out to a gunsmith so we don't have a source for tools to sell over the counter." 7th & 8th shops: "So that's how the danged thing come off. I'll have to order some of those." 9th shop: The guy said there was no such thing. All Glocks have "staked" sights. When I suggested he pull the 23 he was carrying, break it down and look at the mount, he called me an f___ing know-it-all and told me to leave the store. So I went home, went on line and ordered the dang thing, and will be patient for a couple of days 'til I can switch out to the new sight. $12.95 +4.00 shipping. And $50 for gasoline and Pepcid. Remember where I said, "Knowledgeable operators" up at the top? Erase that for me, please.
