I owned one, sold it, and regretted it enough to look for a replacement. This January I put in an order with my favorite FFL. Three months later they still couldn't find me one. Hopefully somebody has one in stock somewhere these days, but I gave up on it and bought a S&W 4566. I don't regret the switch at all, the Smith is a solid pistol, but the coolest guy in my novels carries a Baby Eagle .45 so I need to get one again someday.
I would suggest that if you can't find the .45 in stock anywhere, go with the 9mm or .40. At the very least you get larger magazine capacity.
