Frequently Asked Questions
Glock 34 Gen 3 for sale
What gen Glock 34 is best?
Gen5 is generally considered the best, offering a flared magwell, improved barrel, ambidextrous slide stop, and MOS optics compatibility. Gen4 suits those wanting interchangeable backstraps. Gen3 remains reliable and affordable. For competition shooting, Gen5 MOS is the top choice.
Is the Glock 34 Gen 3 worth it?
Worth depends on your use. Gen3 models typically cost around $600, making them affordable entry points for competition or sport shooting. It's a reliable 9mm striker-fired pistol with strong aftermarket support. If you don't need Gen5 improvements like the flared magwell or ambidextrous slide stop, the Gen3 performs well.
What is the point of a Glock 34?
Glock designed the 34 as a competition pistol with a 5.32-inch barrel and longer sight radius than the G17, delivering improved accuracy and velocity. It's also used for sport shooting, tactical training, and duty carry. The full-size frame and 17-round capacity make it versatile across applications.
Is the Glock 34 Gen 3 Optic ready?
Gen3 Glock 34 slides are available optics-ready directly from Glock. The Glock Shop offers a G34 Gen3 Spare Slide with a factory MOS cut, allowing straightforward red dot mounting without custom gunsmithing. We carry related parts and accessories on our marketplace.
When was the Glock 34 Gen 3 made?
The Glock 34 was introduced in 1998. Collectors retroactively labeled this era "Gen 3," though Glock didn't officially use generational designations until Gen 4 launched around 2010. Gen 3 production continued well beyond the early 2010s, only being phased out more recently with the introduction of newer models.
What frame does the Glock 34 use?
The Glock 34 uses a full-size frame, the same as the Glock 17. It is made from Glock's high-strength polymer and is available in multiple generations, with Gen 5 being the current production version.
