Yeah for weight savings it would have to go with no rail, but the rail may help to sell better. I was thinking with the bevels on the LTT frame that on the compact it would allow one to get the fingers a little higher into the trigger guard to make the most of the real estate. I probably wouldn't mind trying out a Cen Tac slide and barrel for my LTT frame. My only concern is if a slightly shorter slide alone is enough for a ton of people to own both. Some will, but I would think more people would choose one or the other. And are people who are buying the LTT, because they are wanting the shorter slide?
