Ruger MAX-9 9mm vs Sig Sauer P365 9mm

Two micro-compact 9mms with the same 5.5 lb trigger pull. The Ruger MAX-9 9mm holds 12 rounds to the Sig Sauer P365 9mm's 10, is 0.11" narrower (0.95" vs 1.06"), comes optic-ready where this P365 does not, and adds a manual safety alongside its trigger safety and internal striker blocker. The P365 is the smaller package — 5.8" long and 4.3" tall against 6.0" and 4.52" — and 0.6 oz lighter at 17.8 oz. MSRP is $439 against $519.99.

Pick the Ruger MAX-9 if:

• You want 12 rounds instead of 10 without moving up a size class
• A factory optic cut matters; the MAX-9 is optic-ready and this P365 is not
• You want a manual thumb safety, and the flattest frame here at 0.95" (0.11" narrower)
• MSRP is $80.99 lower ($439 vs $519.99)

Pick the Sig Sauer P365 if:

• It is the smaller gun in every external dimension that counts: 5.8" long and 4.3" tall vs 6.0" and 4.52"
• At 17.8 oz it is 0.6 oz lighter in the pocket or on the belt
• XRAY3 day/night sights front and rear come standard
• Sig publishes a 4.9" sight radius; Ruger does not publish one for the MAX-9

The MAX-9 wins on capacity, width, optic cut and price; the P365 wins on outright size, weight and sights. If a red dot or a thumb safety is on your list the Ruger settles it, otherwise it comes down to two rounds against a genuinely smaller gun.
