Went to my LGS to just see what they had in stock... Ran into a .357 Sig Glock 31 with a 15 Degree non-LCI extractor and dirty, dim night sights. I asked him about looking at the internals and he said "Don't wanna take them Glocks down, almost impossible to get back together. Don't dry-fire it either." (Which, he had a sign on the counter about dry-firing so that's understandable.) Looked like a good find and should have been a decent price, I was thinking $350-$400, considering it was fairly worn and the grip was shiny.. Asked the price, guy replied with " She's $540 but I can do $525 for you." and he would not go any lower for the life of me! I replied, "Alrighty, have a good day, sir." Some people are just crazy!
