Glock G20 Gen5 MOS 10mm vs Glock G29 Gen5 10mm

One cartridge, two carry propositions. The Glock G20 Gen5 MOS 10mm holds 15+1 behind a 4.61" barrel; the Glock G29 Gen5 10mm holds 10+1 behind a 3.78" barrel. The G29 is 1.14" shorter overall (6.93" vs 8.07"), 0.98" shorter in height (4.53" vs 5.51") and 1.59 oz lighter (26.81 oz vs 28.4 oz), but both are 1.38" wide, so the G29 hides at the grip and the muzzle, not at the belt line. Sight radius falls 1.02", from 6.93" to 5.91". The G20 ships optic-ready and the G29 does not. Trigger pull is 5.8 lb on both and MSRP is $650 against $647, so neither of those is a real difference.

Pick the Glock G20 Gen5 MOS if:

• You want 15+1 rather than 10+1, five more rounds
• You want the factory optic cut and the longer 6.93" sight radius
• The gun rides in a field or duty holster where 8.07" of pistol is not a problem

Pick the Glock G29 Gen5 if:

• Concealment drives the choice: 0.98" less height and 1.14" less length
• You want the lighter of the two at 26.81 oz
• You are content with the white dot and white outline irons, since this G29 has no optic cut

Width is 1.38" on both, so what the G29 buys you is grip and slide length. What it costs you is five rounds, 1.02" of sight radius and the ability to mount a dot without slide work.
