How ya' doin' today, Troy?
I don't mean to get emotional about grip screws, but I really got to disagree with you.
True, slotted grip screws can be horrible, but the alternatives are worse. Allen heads will strip out quicker than any other design. This is especially true if you decide to use a little dab of "Locktite" on them to keep them from backing out (which can happen with 1911s).
Slotted screws will outlast any other design and are more positive, PROVIDED you use the CORRECT SIZE screwdriver! I know, I know, we've ALL been guilty of using the wrong size scrwedriver from time to time (including yours truly). However, any gun owner with half a brain will (eventually) make sure that he's got a few dedicated screwdrivers in his cleaning kit or range bag. I like the look of the allen heads, too and I had stainless steel allen heads on my 1911 for years until I finally got some sense and went back to the "old fashioned" slotted screws, but they're the best way to go. The old school gun guys knew what they were doing, trust them!
