Got my first Glock today. A police trade in Gen 2 G22. My neighbor bought it from a local shop and his wife Freaked, so I got it from him for $280 with three 15 rd mags. Haven't shot it yet due to the massive ice storm that hit last night, but it sure feels good!! Lots of holster wear, but the trigger feels amazingly crisp and smooth. Anything a new Glock owner should look at with a used gun of unknown round count? Pics to come when I remember where the heck I put my camera after vacation!
