I strongly choose the 9mm caliber, used with proper ammo with the ideal ballistics and grain fat, for almost any use. The 9mm G19X hybrid is a pleasant normal-intent use gun, effectively combining the compact slide in the G19 with the for a longer time total-measurement frame of the G17. https://glock-g19x35566.glifeblog.com/30209014/detailed-notes-on-glock-34-gen-5
