I have a G17 that I may want to mount a scope or red dot on and would like some input from anyone who has done this. I've seen a couple of different mounts to do this here and here. http://www.glockworld.com/item/42277_The_Accessories_Scope_Mounts_T_H_E__Accessories_Black_.aspx

If possible I'd like to find out your thoughts on this type of mount as well as optics to go with it. Pictures would be very nice also.

Until recently, elevated frame mounts were the only game in town as the optics were not capable of withstanding the g-forces encountered when mount to the slide, and the optics were much heavier and would have negatively affected the cycling. With the sight elevated this high above the bore axis, at any distance other than the sweet spot at which it was sighted in, POI is way off from POA. Also, you have the problem of slide-to-frame alignment; as an example, the loose fit of a Glock slide to it's frame results in considerable inconsistency of slide/frame alignment from shot to shot, and between loaded and unloaded chambers -- to the tune of inches at only 7yds.

If you are talking about a big scope, you may have no choice, but if you are talking about one of the new, rugged miniature RDS, you will have a much more functional/accurate weapon if you mount to the slide (preferably milling the slide). Have you looked at the WarriorTalk forums at http://www.warriortalk.com/forumdisplay.php?205-Red-Dot-Sighted-Pistols ?

Thank you. Never really thought about how well the mount would work but you have definitely made good sense of this. I don't think I would like this as much now. Thanks for the info.
