Sig Sauer P365-Fuse 9mm vs Sig Sauer P365 X-Macro 9mm

Both are P365-family 9mms at the same 1.1" width, both optic-ready, with grip heights within 0.1" (5.1" vs 5.2"). The differences are capacity and slide length. The Sig Sauer P365-Fuse 9mm holds 21 rounds to the Sig Sauer P365 X-Macro 9mm's 17, and runs a 4.3" barrel against 3.1" — 1.2" more barrel, 0.6" more overall length (7.2" vs 6.6") and 0.9" more sight radius (6.0" vs 5.1"). That buys 1.6 oz of weight (23.1 oz vs 21.5 oz). The Fuse's listed trigger pull is 0.2 lb lighter (5.3 lb vs 5.5 lb), it ships with three magazines to the X-Macro's two, and its MSRP is $30 lower ($799.99 vs $829.99).

Pick the Sig Sauer P365-Fuse if:

• You want 21 rounds instead of 17 in a grip that is within 0.1" of the same height
• You shoot irons and want the longer 6.0" sight radius rather than 5.1"
• Three magazines and a $30 lower MSRP ($799.99 vs $829.99)

Pick the Sig Sauer P365 X-Macro if:

• You want the shorter 6.6" overall length and 1.6 oz less weight (21.5 oz vs 23.1 oz) on the belt
• You prefer XRAY3 day/night sights front and rear over a green fiber-optic front with a serrated black rear
• 17+1 is enough and you would rather not carry a 4.3" slide

The grip, width and optic cut are effectively the same gun, so the decision is the 1.2" of extra barrel and four extra rounds on the Fuse against 0.6" less length and 1.6 oz less weight on the X-Macro.
