Glock G17 Gen5 MOS 9mm vs Glock G19 Gen5 MOS 9mm

Same trigger at 5.8 lb, same 1.34" width, same fixed sights, same optic cut, same three magazines and the same Black nDLC finish. This is purely a size-and-capacity decision. The Glock G17 Gen5 MOS 9mm holds 17+1 to the Glock G19 Gen5 MOS 9mm's 15+1, runs a 4.49" barrel against 4.02", and is 0.67" longer (7.95" vs 7.28"), 0.43" taller (5.47" vs 5.04") and 1.06 oz heavier (24.87 oz vs 23.81 oz), with a 0.47" longer sight radius at 6.65" vs 6.18". MSRP is $745 for the G17 and $636 for the G19.

Pick the Glock G17 Gen5 MOS if:

• You want two more rounds without changing magazines (17+1 vs 15+1)
• You shoot at distance and want the 6.65" sight radius and 4.49" barrel
• The gun lives in a duty holster or a range bag, where 0.67" and 1.06 oz cost you nothing

Pick the Glock G19 Gen5 MOS if:

• You conceal it, where the 0.43" shorter grip height (5.04" vs 5.47") is what actually prints
• You want it $109 cheaper at MSRP ($636 vs $745)
• You want 1.06 oz less weight while keeping the same optic cut and trigger

Every feature that usually decides a Glock comparison is identical here. The answer is whether you carry concealed, where the G19's shorter grip wins, or shoot mostly from a duty rig, where the G17's two rounds and longer sight radius do.
