Very nice, though I wouldn't call either Sig a 1911.
What is a 1911? Does it have to be 45 and 38 Super only?
What is a proper Commander/Officer clone? Is it the chambering, the size, the overall function?
Does it need to have 80-90% parts interchangeable with other "established" 1911s?
What exactly is a Series 70 and 80 these days?
Does it NEED to have an internal extractor?
Can you make the frame out of alloy?
Is the Les Baer monolith a 1911?
