I think it's kind of like Les Pauls or pretty much anything from the Gibson custom shop these days. Their customers tend to be people who already own other Gibson guitars and still have sizeable excess incomes to let them buy more. It's actually a cause for concern at Gibson because their market is literally aging out.
It's possible that the single stack .45 ACP 1911 is making a huge comeback, but I think it's mainly people who already own and like 1911's in .45 ACP buying them. I'm sure there's some crossover from people who bought EDC type guns maybe spending some spare cash on a .45 ACP version, but it can't be that high.
I think overall Wilson is making a lot more EDC based guns than 1911's these days. Just my guess.
