You have mentioned you already have a SR9C for carry and home defense. So why not get something along a different line? An all steel target pistol perhaps, instead of continuing on with more polymer? My only "argument" with polymer pistols is they have no soul. They're fine for their intended purpose, which is a knock around and carry self defense service pistol. You have already successfully filled that need. There are a lot of nice, well crafted guns that would fit your budget, or else are just slightly above it. I'm not talking $3K "Barbecue 1911's" either. There are many nice 1911's in the $600.00 to $850.00 range that are very well made. There is also the CZ-75 line that can be had in both black, as well as Stainless Steel. In both polished and matte finish no less, in that same price range.
If you can spend a bit more the Browning Hi-Power is available in a bright blued finish. along with nice checkered Walnut grips. It's a pistol of heirloom quality, that you will be able to hand down to your next generation. Even the E.A.A. Witness line starts out in the mid $600.00 range, and offers all steel construction in several finishes and sizes in both compact and full size models. Any of these weapons would make a nice addition to your collection, and give you something a little different.
