Based in many ways on the preceding Glock 29 design, the Glock 30 is another fine example of pistol handiwork from Gaston Glock's Austrian firm. The system is chambered to fire the .45 ACP caliber round which remains popular in the United States of America. Outwardly, the Glock 30 retains many of the features found on the Glock 29 and differences between the two are subtle. The feed system can accommodate magazines in 9 (flush-fit), 10 and 13 round magazines. The thirteen round magazine from the Glock 21 can be used in the Glock 30 as well.
Developed in the late 1980's, the system has proven popular with self-defense units in the USA. Integrated sites are of the fixed variety and mounted on the front and rear of the weapon. The design itself offers up conceal ability and is highly portable, termed as a sub-compact handgun that can satisfy many a defense role.
