I suspect it would be difficult to send the slide and barrel but you never know.
If I was in the market i would be tempted. Accuracy v price is an interesting one. I think you hit diminishing returns relatively quickly, above which your paying for fit, finish and exclusivity. For this one, it is the price of a decent Tanfoglio and a fraction of what many spend on a custom 1911, so I would be willing to spend the extra for even a small incremental improvement, recognizing of course the shooter is always the limiting factor.
