Well, me and the gf's daddy made a little deal. I had a Glock 27 pretty much stock that just rides in the last ditch bag and he had an older Glock 17 with 5 mags that was a safe queen. Both guns were in like new shape and we have both been very happy with the deal. Somethinhg of interest was when cleaning the 17 I noticed it is a 2 pin version but is a thrid generation gun (having a railk and finger grooves). I told him about it and he called BS; seems he never noticed it only had 2 pins and he is a Glock Armorer. He said he has never heard of this, any else?
