I did have an experience with glockdoc, my dad had him clean and inspect a glock 26 he had just bought at a fort wayne show. He told dad that it was a special run that was made for the secret service because the fingergrooves were different. He said it was worth at least $850 but it was ok to shoot it. Now when I got home I tried to find something on the web and at glocktalk...nothing, but people making fun of me. Now maybe someone here might know this is true but I think it is bs! of course my dad wont sell the gun because he thinks its worth $1000!
