I will not presume to answer for the Mouse, but can offer the opinion that the Sig 1911s are great pistols. The two things that tend to bother a lot of folks are the squared slide profile (does not look like the one in your photo has that though, being a traditional profile) and the external extractor. External extractors are fine, but do run against tradition in 1911s.
On the plus side for the Sigs are the fact that they tend to come complete with front strap checkering, extended controls, night sights, nice grips, checkered steel main spring housings and decent triggers. Mine is a Sig Railed Nickel full size 1911 and has been a very nice pistol for the $900 I paid for it.
Edit: CM did tell him exactly how he feels and to his credit, was pretty kind about the slide profile and other mods. CM is definitely becoming a big teddy bear now days.
