So planning ahead for tax return, pending nothing coming up, I was thinking of getting a new horse for the stable. I'm torn between two. I've been wanting to get another .45 and narrowed it down. I'm looking at getting either on of the SIG 220 variants or a Springfield Full-size MC Operator 1911. Any ideas?
