OK, here is the voice of dissension.
There is nothing wrong with see through scope mounts except for personal prejudice. I have them on 2 Encore barrels, I don't find the scope to be too high and they are useful as in the case of a ground hog heading for its hole at top speed I shot at around 6 feet with my 30/06. In my opinion, the thing that looks dumb is a scope permanently mounted on an Encore barrel with the front sight still in place and useless. The bad news is that for Encore handgun barrels, the rear sight has to be removed to mount a scope unlike rifle barrels.
Another scope mounting solution that permits use of iron sights and lets one mount the scope low, is to use Warne Weaver style bases with quick detach rings (the scope can be removed in a few seconds). This also allows one to switch scope between barrels; a useful feature when Encore & Contender barrels have been fruitful & multiplied (how does that happen?).
