Glock G29 Gen5 10mm vs Glock G40 Gen4 MOS 10mm

These sit at opposite ends of the 10mm line, and almost every spec reflects it. The Glock G40 Gen4 MOS 10mm runs a 6.02" barrel against the Glock G29 Gen5 10mm's 3.78" and is 2.56" longer overall (9.49" vs 6.93"). It also carries five more rounds (15 vs 10), weighs 8.64 oz more (35.45 oz vs 26.81 oz), stretches sight radius from 5.91" to 8.31", breaks 0.4 lb lighter (5.4 lb vs 5.8 lb), and is optic-ready with an adjustable rear sight. MSRP is $193.00 apart ($840.00 vs $647.00). Both use Safe Action striker triggers, interchangeable backstraps and three magazines.

Pick the Glock G29 Gen5 if:

• You intend to carry it: 6.93" long, 4.53" tall and 8.64 oz lighter at 26.81 oz
• $647.00 against $840.00
• Ten rounds and fixed white dot / white outline sights are enough for the role

Pick the Glock G40 Gen4 MOS if:

• You want the 6.02" barrel and the 8.31" sight radius, 2.40" longer than the G29's
• Fifteen rounds instead of ten
• You need the MOS optic cut, an adjustable rear sight and the 5.4 lb trigger

The G29 is the only one of the two that conceals, and the G40 is the only one with a 6.02" barrel and an optic cut. Decide whether this gun rides on your belt every day or goes in the field, and the 8.64 oz and 2.56" settle the rest.
