Design & Background

The Glock 29 was developed as a subcompact 10mm pistol, giving shooters access to one of the most powerful mainstream semi-automatic handgun cartridges while keeping the pistol relatively compact. It is essentially the smaller sibling to the full-size Glock 20 10mm pistol.

The Gen 3 version retains Glock’s proven design features:

• Polymer frame
• Steel slide with durable finish
• Locked-breech short recoil operation
• Polygonal barrel rifling
• Striker-fired trigger system

Superior versatility is available with this high-performance, 10mm AUTO pistol. With reduced dimensions compared to the standard size GLOCK 20, the subcompact GLOCK 29 is also suitable for concealed carry. In addition to the use as a backup weapon for hunting, more and more security personnel on patrol appreciate the comfortable firing characteristics and the grip ergonomics of the G29 10 mm with its standard 10 round magazine.
