What I want is for Glock to offer the option of the Finger Grips for thsoe who want them. And to offer a Straight Frame for those like me who prefer not to have those grips line up with the middle of my fingers. If I wanted them then I could add their old Add on in the location I wanted to make sure I coudl still have a proper grip.
There is another option. There are plenty of factory refurbished police trade-ins, that have the 2nd generation frames (no finger grooves, no rails). These are carefully inspected, tested, cleaned, and all parts are stripped down and replaced, if needed. They undergo a final cleaning and refinishing, and are as good as new. Usually you can find them for under 400 bucks, if you look carefully.
