On this part of what you ask about....
There are a few exceptions but basically:
Full size/Gov't model: 5" barrel & full size frame
(exception to this is a Longslide - this one has a longer 6" barrel & slide with full size frame)
Commander size: 4.25" barrel (so shorter slide) & full size frame
Officer size: shorter barrel with differing lengths down to 3" & smaller frame too (grip is shorter in length & does not accept standard 1911 mags)
I do not have much experience with Officer sized 1911's (prefer mine to have no shorter barrel than 4.25") but wanted to make the point that if you are looking at getting a Commander sized pistol (as you state above that you are looking at a 4.25" barrel) - those have standard/full sized frames.
They accept standard 7 round 1911 magazines & the grip length is the same as a Gov't size 1911 (so they take the same grips too).
