Glock G19 Gen5 9mm vs Sig Sauer P365 X-Macro 9mm

The Sig Sauer P365 X-Macro 9mm holds two more rounds than the Glock G19 Gen5 9mm (17 vs 15) in a smaller, lighter package: 6.6" long and 1.1" wide against 7.28" and 1.34", and 2.13 oz lighter at 21.5 oz vs 23.63 oz. The Glock trades that for barrel and sight radius — 4.02" vs 3.1" and 6.02" vs 5.1" — plus three magazines in the box instead of two. The X-Macro ships optic ready with XRAY3 day/night sights and a 5.5 lb trigger; the standard Gen5 G19 has fixed sights, a 5.8 lb trigger and no optic cut. MSRP is $829.99 for the Sig against $647 for the Glock.

Pick the Glock G19 Gen5 if:

• You want the longer 4.02" barrel and 6.02" sight radius, close to an inch more than the Sig in both
• You want to spend $182.99 less ($647 vs $829.99) and get a third magazine
• A 1.34"-wide gun carries fine for you

Pick the Sig Sauer P365 X-Macro if:

• You want 17+1 in a gun 0.68" shorter and 0.24" narrower than the G19
• You want a factory optic cut and XRAY3 day/night sights rather than fitting both
• You want 2.13 oz off the belt (21.5 oz vs 23.63 oz)

The X-Macro is the more capable carry package as it sits: more rounds, less gun, and the optic cut already done. The G19 is the cheaper one, with the longer barrel and sight radius and an extra magazine.
