Glock G43X 9mm vs Sig Sauer P365 X-Macro 9mm

Both frames measure 1.1" across, and overall length is within 0.1" (6.5" vs 6.6"), but the similarity stops there. The Sig Sauer P365 X-Macro 9mm holds 17 rounds to the Glock G43X 9mm's 10, ships optic-ready where the G43X does not, and lists $291.99 more ($829.99 vs $538). The G43X is 2.8 oz lighter (18.7 oz vs 21.5 oz), 0.16" shorter in height (5.04" vs 5.2") and carries 0.31" more barrel (3.41" vs 3.1") with the longer sight radius (5.24" vs 5.1").

Pick the Glock G43X if:

• It is 2.8 oz lighter (18.7 oz vs 21.5 oz), which is the number you feel on a belt all day
• The grip is 0.16" shorter (5.04" vs 5.2"), so less of it prints
• You want the longer barrel and sight radius of the two (3.41" and 5.24" vs 3.1" and 5.1")
• MSRP is $291.99 lower ($538 vs $829.99)

Pick the Sig Sauer P365 X-Macro if:

• Seven more rounds per magazine (17 vs 10) settles it
• You get that capacity in the same 1.1" width and within 0.1" of the same overall length
• It is optic-ready from the factory; the G43X is not
• XRAY3 day/night sights front and rear come standard

Same width, near-identical length, very different magazines. Seven rounds and a factory optic cut against 2.8 oz, a shorter grip and $291.99.
