Glock 26. You can make the Glock 26 bigger (using the Glock 19 mags and grip extension) but you cannot make the Glock 19 smaller.
A Glock 26 is very versatile. Easy to CC when using the stock flush fitting mags, but when you can carry and aren't concerned about printing then you can use either the G26 mags with pinky extension or the G19 mags with the grip extension.
