Frequently Asked Questions
Glock 34 Gen 4 MOS for sale
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, improving accuracy and velocity. Sport shooters and tactical users favor it for its balance. It accepts standard 17-round magazines and comes in standard or MOS optics-ready versions.
Which generation Glock 34 is best?
Gen4 and Gen5 are the most popular choices. Gen5 adds ambidextrous slide stop, flared magwell, and a better barrel, while Gen4 costs less. Gen3 users often prefer its trigger feel. For competition shooting, Gen5 is the current standard, but all three generations perform reliably.
Is Glock 34 more accurate than Glock 17?
The G34's longer 5.31-inch barrel and extended sight radius provide a marginal accuracy advantage over the G17. Both fire the same 9mm ammunition with identical reliability. For most shooters the difference is negligible, but competitive shooters favor the G34 where small precision gains matter.
Is a Glock 34 a good competition gun?
Yes. Glock designed the G34 specifically for competition. Its longer barrel and slide reduce recoil and muzzle flip, and the extended sight radius improves accuracy. It is reliable, highly customizable, and widely used in USPSA and IDPA. Optics-ready variants are currently available.
What optics fit a Glock 34 Mos?
Glock 34 MOS accepts optics via adapter plates included with the pistol. Compatible optics include the Trijicon RMR, Holosun 507C X2, Vortex Venom, and Leupold DeltaPoint Pro. Each requires a specific adapter plate matching its footprint. Confirm compatibility with your chosen optic before purchasing.
Does GLOCK Mos fit RMR?
Yes, Glock MOS pistols accept the Trijicon RMR using the included adapter plates. The RMR mounts to the plate, not directly to the slide. Most full-size MOS models support this. Check which adapter plate matches your specific MOS variant before purchasing.
Does Holosun fit Glock Mos?
Yes. Holosun optics fit Glock MOS pistols. The SCS-M-GR mounts directly to full-size MOS slides without adapter plates. Other Holosun models use included MOS adapter plates. Compatibility depends on the specific Holosun footprint and your MOS variant, so verify before purchasing.
Which Glock MOS plate for RMSc?
Slimline Glock MOS pistols (43, 43X, 48) accept the RMSc directly with no adapter plate needed. Full-size MOS models (G17, G19, G34, G40, G41, G45, G47) require a separate RMSc adapter plate, as their cutout is larger than the RMSc footprint.
What optic plate comes with GLOCK MOS?
Glock MOS pistols ship with one adapter plate compatible with Trijicon optics. For optics with a different footprint, a separate adapter plate must be purchased.
What red dot fits a GLOCK MOS without an adapter plate?
The Holosun SCS mounts directly to full-size Glock MOS slides without an adapter plate. On slimline MOS models like the G43X and G48, optics with the Shield RMSc footprint mount natively. Most other red dots require an adapter plate on full-size MOS pistols.
What plates does the GLOCK MOS come with?
Glock MOS pistols now ship with a single MOS adapter plate. Specific plates included vary by model size. Additional plates are available separately to support other optic brands and footprints, including Trijicon RMR, Leupold DeltaPoint Pro, Eotech MRDS, and C-More.
Did GLOCK make a Gen 4 MOS?
Yes. Glock produced Gen4 MOS models including the G17, G19, G34, G35, G40, and G41. These pistols feature the Modular Optic System, allowing miniature reflex sights to be mounted via adapter plates without milling the slide.
What is the difference between Glock 34 gen 4 and gen 5?
Gen5 G34 features an improved trigger with updated lockwork and Glock's accuracy barrel for tighter groups. Gen4 offers interchangeable backstraps for three grip sizes. Gen5 typically costs around $120 more. Both are full-size 9mm competition pistols; Gen5 comes MOS-only while Gen4 has standard and MOS variants.
