I carry my G26 better concealed than I do my G32 (same size as the G19).
IMHO, I would stick with the G26 for CCW and save your money to buy the G19 or other pistola later. You will not CCW the G19 better than the G26. The G19 is a good firearm, but between the two, the G26 is easier to CCW than G19.
Good Luck & Welcome to the world of Carrying!!
