Question 3

How does the Glock Safe Action® System work on this model?

Accepted Answer

The Glock Safe Action® System in the Glock 45 Gen5 MOS is a passive triple-safety mechanism designed to prevent accidental discharges while ensuring the pistol is always ready to fire when intentionally engaged. This design eliminates external manual safeties without compromising operator safety.


 	
Trigger Safety (Primary Level)A center-lever safety built into the trigger blade ensures the pistol cannot fire unless the trigger is deliberately pulled straight to the rear.

 	
Firing Pin Safety (Internal Block)This vertical firing pin block prevents the striker from moving forward unless the trigger is fully pressed, protecting against discharge if dropped.

 	
Drop Safety (Trigger Bar Control)The rearward motion of the trigger bar maintains the striker in a partially tensioned state until a complete trigger pull is registered, mitigating unintentional discharges from shock or inertia.

 	
Fully Automatic Re-EngagementAll three safeties automatically reset when the trigger is released, requiring no manual activation and making the pistol consistently ready for the next shot.

 	
Simplified Manual of ArmsWith no external levers, the Safe Action System allows for straightforward use under stress while meeting global safety standards for modern duty pistols.

Compact Slide Enhances ConcealabilityThe slide length is the same as the Glock 19, making holster carry easier under clothing without the added bulk of a full-size slide.

 	
Slim Profile with No Finger GroovesThe Gen5 grip design is flat and ergonomic, reducing printing through garments while maintaining a secure hold.

 	
Optics-Ready for Fast Target AcquisitionRed dot sights mounted on the MOS cut allow for quicker aiming without sacrificing concealment, especially when paired with low-profile optics.

 	
Full-Size Magazine and Grip ControlUnlike smaller handguns, the G45 provides a secure full grip, which significantly improves accuracy, recoil recovery, and overall confidence during defensive use.

 	
Compatible with Concealed HolstersThe model works well with IWB (Inside Waistband), AIWB (Appendix), and OWB (Outside Waistband) holsters from leading brands due to its standardized Glock dimensions.

Question 5

What magazines are compatible with the Glock 45 Gen5 MOS?

Accepted Answer

Question 8

How does the recoil and shooting feel compare to other Glock models?

Accepted Answer

The Glock 45 Gen5 MOS delivers a balanced recoil impulse and smoother shooting feel thanks to its crossover design. The full-size grip allows for better control, while the compact slide reduces reciprocating mass, making follow-up shots faster and more accurate.


 	
Improved Recoil Control with Full-Size FrameThe longer grip allows for a more stable two-handed hold, distributing recoil force more efficiently and reducing muzzle flip.
