My favorite 1911 is a springfield built by Rob leatham when he ran the springfield armory custom shop 30some years ago. It is a .45 and slicker than snot and accurate. I bought my first 9mm 1911 last year, a commander size alloy frame. I like it a lot, enough to actually want another 5" steel 9mm, not as a carry gun but just a range fun gun. If I could justify the cost I would build a shortened slide with a barrel comp for 5" overall.
Just for fun ya know...
