It's generally reccomended not to get a tiny pistol as your first pistol as it is much harder to learn on smaller pistols. A compact sized (glock 19 as you put it) pistol is generally the best compromise of easy for beginners to carry and shoot. Caniks don't have a great rep, but are cheap. Other cheap alternatives are the Taurus g3c, the Berretta APX compact, the ruger RXM, and the IWI Masada. Of those options I like the IWI masada and the taurus g3c the best but you should either go to a rental range and try them or finger fuck em at a shop.
