Russell,

Not sure how much material is left between the bottom of the dovetail and the firing pin tunnel, but in my standard installation the bottom of the dovetail has very little room above the slide serrations. Not sure if you would care about getting into those, but a little melt would be pretty cool. While my front sight is not what I would call excessively high, it can be a little hard in some leather. The Brown barrel that fit to compliment my Rowlands is looking like for all loads, my rear is down a little in the notch, so I may have a little wiggle room to reduce my front sight a bit.

Along the same lines, the one thing I really like about the Novak adjustable over a Bomar is that the sight body really protects the notch/blade from wear or loss of bluing. It really is a joy to have a rear blade that does not require touch-ups.
