Being a total left brained analyst I made up a spreadsheet to compare various dimensions for a new carry gun. These forums don't format columns well but fwiw:
Firearm | Capacity | Barrel" | Length" | Height" | Width" | Slide Width" | Sight Radius" | Weight Unloaded
G19 | 15 | 4.02 | 7.28 | 5 | 1.34 | 1 | 6.02 | 21.52
G48 | 10 | 4.17 | 7.28 | 5.04 | 1.1 | 0.087 | 5.98 | 18.48
P365 | 10 | 3.1 | 5.8 | 4.1 | 1 | .9 | 4.9 | 17.8
P365XL | 12 | 3.7 | 6.1 | 4.8 | 1.1 | .9 | 5.6 | 20.7
I only showed the standard magazines, obviously the G19 can be equipped with larger mags, the G48 now with a 15 round mag and the Sigs both have 12 and 15 round mags available that increase the overall height.
Wow, the slide on the G48 is really narrow
