Don't own a Glock yet - am looking for a used 3rd Gen model 20. Going to make a .224 Boz conversion. We do sell plenty at the store. I will tell you Glock does put on a hell of a party at the Shot Show. I have been to a couple and will not be missing this years. Getting in the door takes a bit as you shake everyone up the corporate ladders hand. The funny thung about the line is as you go down the line the southern drawl turns into German tainted English. The last hand you shake is Gaston's as he thanks you for buying his product.
