Glock G26 Gen5 9mm vs Sig Sauer P365 9mm

Both 10+1 in 9mm and built for deep concealment, but the P365 is the smaller gun by every measure: 0.62" shorter, 0.24" thinner, and 3.89 oz lighter (17.8 oz vs 21.69 oz). The G26 trades that size for Glock magazine compatibility — it accepts standard G19 and G17 magazines for higher-capacity reloads, which the P365 cannot match across platforms.

Pick the Glock G26 Gen5 if:

• You want the option to load G19 (15+1) or G17 (17+1) magazines for spare reloads — the P365 has no equivalent
• You want the Glock aftermarket for holsters, sights, and parts
• You want the wider grip for a more controllable hold (1.3" vs the P365's 1.06")

Pick the Sig Sauer P365 if:

• You want a slim 1.06" frame — 0.24" thinner — for pocket carry or inside-the-waistband under a tucked shirt
• You want 3.89 oz less weight for all-day carry
• You want a 0.62" shorter overall length for the smallest concealment footprint

Both are striker-fired polymer 9mms at 10+1. The G26 trades size for cross-platform magazine flexibility; the P365 trades that flexibility for the smallest viable 9mm package.
