STI has a model like a CCO but I can't recall the model name.
S&W has announced a CCO format model called the
SW1911 Compact ES. with the usual Novak low mount
'carry' three dot sights, beavertail grip safety, etc. It has a
stainless steel slide and the scandium alloy frame is black for
a two-tone. 29.6 oz. empty.Probably hit distributors this
summer.
SIg Sauer's C3 is the version with an Alloy frame, there are 3 others
in like size with the steel frame - note all of these have the checkered
front strap in the grip area of the frame.
