Is there people out there that would love to see Sig produce a High-Cap 45ACP in their P245 or in the P226/P228 line of pistols.  With the sunset of the Brady Bill it would seem that Sig would be willing to produce a line of pistols similar to the Para Ordnance.  I've owned two Sigs now for almost 10 years, that being the P220 and the P226, and cannot bring myself to buy anything else.  I have thought about the Para Ordnance P10 and P12 pistols, but I keep holding out for the chance for Sig to produce something similar.

Any feedback from fellow Sig owners (Pros and Cons) is welcome.

I just think that most Sig 220 shooters and 1911 shooters are satisfied with 7-8 rounds in the magazine, especially for a .45  I am very content with 8 rounds in my 220 so I personally don't see the need for and extra few rounds.

you can buy factory non-flushfit 10rd mags from sig.

The P221 is a concept that Sig made a few years back, its a double stack P220.  Don't expect it to get built though.
