I have tried searching for this, and am unclear on the situation- The local Gander Mountain has a Glock 17 w/2 magazines for sale; asking price is $449 (I asked about any cheaper pricing, and they offered to knock $10 off the price- pretty serious, these guys) This gun has no fingergrooves, and from what I can tell, only one pin above the trigger, crossing through the frame. I am trying to understand the whole one pin, two or three pin issue- I like the fact that this frame has no finger grooves, but have some concerns about weakness, or possible problems with the one pin issue, which I have read a little bit about. The serial number on the gun starts with the letters "KE" if I remember correctly. Could you please explain to an old guy new to Glocks what this is all about, and should I pass on this gun? The only other issue I can see with it is the rear sight appears to have been "mashed" for want of a better word where it fits into the dovetail on one side, like someone tried to force it over with an improper tool set up. thanks!
