Just purchased one of these week before last. I was not disappointed. Added, Trijicon sights, Hyve mag release, Hyve Monarch Trigger, Hyve aluminum slide back plate, Hyve guide-rod and spring, Vickers Tactical slide release, Hyve aluminum magazine base plates and a Streamlight TLR-6. I have been a huge fan of the new line of Glocks, having purchased and carried the 42 and 43 in similar to the above configurations, I can easily say this one is one of my all time favorites. Perfect size for me, holds 10 without mag extensions, off the charts reliability.
