The quote from Brister as I recall was written in American diction "sure is hard to close" is more American phrasing than English. Us non native speakers tend to notice these details.

As to the subject matter at hand:

Innovation as in laser engraving, CNC machinery and the like, is a good thing, as long as the people using it are gunmakers. To draw a parallel from experience, computer graphics are a good thing when used by trained graphic artists. Untrained people tend to overuse the features of software like Photoshop and Corel and I have seen the same unnecessary overuse by some machinists and CAD draftsmen.

I wonder if there is a buying public for an economy double built by gunmakers using modern means but still having that crafted feel and look. That it can be done is not the issue, but how many would buy it. Having seen how many keep a safe full of top guns and hunt with a gas auto I wonder about the size of the potential market.
