It appears that you are looking at all different size 45s.
In the full size catagory The USP along with the SIG P220 & P227 are superb choices. I actually prefer them over the various Smith & Wesson counterparts.
In the mid-size catagory the USPc 45 and HK5c both have almost identical grip size since they are designed around the same magazine. These are incredibly durble sidearms and will take years and years of shooting even the hottest cartridges out there to get them to want to retire
My example above happens to be a USP45ct for suppressor use, but it is available with a standard barrel as well. In his size category you might consider a Shorty 45 from the Performance Center
While I do not currently own a CS45, I do own several CS40s. My CS40s have been converted to use the 10MM Auto cartridge .
I understand you are not looking for a 10MM auto pistol, but the CS10/CS40 pistols are similar in size to a CS45. I have pocket carried the CS10s on several occasions. They are light enough, weighing in at about the same weight as a 357 Magnum Model 640.
In the compact category, I am a HUGE fan of the Boberg XR45-S
Because of the bullpup design, this tiny pistol still has a 3 3/4" barrel
It is a DAO design, but with one of the lightest DAO triggers I have ever tried. It has a external hammer (I now it looks like a striker fired pistol) so it is capable of double strike. The hammer is large and square and flat, certainly not what we are all used to seeing a hammer look like
