Glock G19 Gen5 9mm vs Glock G47 Gen5 MOS 9mm

Same platform, same 1.34" width, same 5.8 lb trigger pull, same three magazines, same nDLC finish. The Glock G47 Gen5 MOS 9mm is simply the bigger gun: 17 rounds against the Glock G19 Gen5 9mm's 15, a 4.49" barrel against 4.02", 7.95" overall against 7.28" — 0.67" longer — and 5.47" tall against 5.04". It weighs 25.93 oz, 2.3 oz more than the G19's 23.63 oz, and its sight radius is 6.65" against 6.02", 0.63" longer. The G47 is cut for an optic and wears a polymer white dot front with a white outline square-notch rear; the G19 Gen5 in this configuration is not optic-ready and uses fixed sights.

Pick the Glock G19 Gen5 if:

• Concealment is the job: 0.43" shorter in the grip (5.04" vs 5.47") and 0.67" shorter overall
• You want the lighter gun at 23.63 oz, 2.3 oz under the G47
• You have no plans for a red dot and are content with fixed sights

Pick the Glock G47 Gen5 MOS if:

• You want a factory optic cut rather than paying to mill a slide
• 17 rounds and a 4.49" barrel suit duty, range or home use
• The 6.65" sight radius, 0.63" longer than the G19, helps your irons

Trigger, width, finish and magazine count are identical, so the decision is entirely whether you want the shorter, lighter gun or the longer one with two more rounds and the MOS optic cut.
