So basically you don't have to compromise on size.
My answer to your similar question was a Glock 22. Full-sized, 15+1 capacity, .40 S&W. I had also considered a Glock 21, which is the full-sized .45.
However, your options of buying decent-capacity semi-autos may be significantly reduced going forward (eithe because of scarcity / inflated prices due to panic buying, or a new magazine capacity restriction).
So I'd say perhaps a Glock 30 (10+1 rounds of .45), a 1911-style .45 (8+1), or a full-sized revolver, perhaps a S&W 686+ in 3" or 4" with 7 rounds of .357 or .38.
