Frequently Asked Questions
Glock 45 MOS for sale
Does the Glock 45 come in MOS?
Yes, Glock offers the G45 Gen5 MOS, which features a Modular Optics System slide for mounting reflex sights.
Is a Glock 45 Gen 5 a good gun?
Whether it's "good" depends on your needs. The G45 Gen5 pairs a compact slide with a full-size grip, suiting both carry and duty use. It's widely trusted for reliability and accuracy. Priced around $600, it offers solid value in the defensive handgun market.
What is the best ammo for a Glock 45 9mm?
Best ammo depends on your use. For defense, Federal Premium HST or Speer Gold Dot offer reliable expansion. For training, Federal American Eagle FMJ costs less. The G45 runs most quality 9mm reliably—test a few brands to find what shoots best for you.
What are the common problems with the Glock 45 Gen 5?
Most G45 Gen 5 issues include occasional feeding or ejection failures, usually caused by low-quality ammunition or limp-wristing. Some users report erratic brass deflection. These malfunctions are uncommon and typically resolve with quality ammunition, proper grip technique, and routine cleaning.
Is a Glock MOS slide worth it?
Worth depends on your optic choice. MOS slides cost around $600–620 versus $500–520 for standard slides plus $100+ gunsmith work. Quality red dots like Holosun mount directly without adapters. Glock's own mounting plates get poor reviews, so consider aftermarket options. Verify your optic's compatibility before purchasing.
How much is the G45 MOS Blue Label?
G45 MOS Blue Label pistols typically run around $477, with pricing varying by retailer and location. Bundle options are available at higher price points. Check local availability for current Blue Label pricing.
How much cheaper are blue label glocks?
Blue Label Glocks typically run $75–$100 below standard retail pricing, depending on the model and sight configuration. Eligible buyers—active or retired military, law enforcement, and first responders—commonly pay around $399–$499 for popular models like the G19, compared to retail prices of $500–$600.
Can anyone buy a blue label GLOCK?
Blue Label pricing is not limited to military, law enforcement, and first responders. Civilians can also qualify by obtaining GLOCK certificates. Authorized Blue Label dealers verify credentials before offering the discount, but note that dealers can only sell to buyers in their home state. Standard retail pricing applies to everyone else.
Will a Glock 45 Mos fit a Glock 19 holster?
Yes. Most Gen5 Glock 19 holsters fit the Glock 45 MOS because holsters index on the slide and barrel, which are the same length on both pistols. The G45 has a longer grip, but that doesn't affect fit. Some older G19 holsters may have issues with the ambi slide stop.
Is a Glock 45 Mos good for concealed carry?
The Glock 45 MOS works for concealed carry but is on the larger side. Its full-size grip aids accuracy and recoil control, though it demands careful holster selection and concealment clothing. Shooters prioritizing easier concealment often prefer the smaller G19 MOS. Your carry method and body type matter most.
What is the difference between a Glock 45 and a Glock 45 MOS?
MOS stands for Modular Optic System. Both fire 9mm with identical frames and capacity, but the MOS variant has factory-milled slide cuts to mount red dot sights without additional gunsmithing. The standard G45 lacks these cuts. Choose the MOS if you want optics-ready capability out of the box.
What optic fits a Glock 45 MOS?
The Glock 45 MOS accepts optics using the RMR footprint via included adapter plates. Compatible options include the Trijicon RMR, Holosun 507C X2, EPS, and SCS MOS. Some optics require specific adapter plates, so verify compatibility with your chosen optic before purchasing.
What footprint does the Glock 45 Mos have?
The Glock 45 MOS uses the standard Glock MOS footprint, accepting multiple optics via included adapter plates compatible with Trijicon RMR, Holosun 507C, Leupold DeltaPoint Pro, and similar patterns. Some optics mount directly without adapters. Confirm your specific optic's compatibility before purchasing.
Does Holosun fit GLOCK Mos?
Yes. Holosun makes optics compatible with Glock MOS pistols. The SCS MOS mounts directly to full-size MOS slides without adapter plates. Other Holosun models fit via included MOS adapter plates. Confirm your specific Holosun model matches your slide's footprint before purchasing.
