Glock G19 Gen5 9mm vs Sig Sauer P365-Fuse 9mm

These two land within 0.08" of each other in overall length (7.28" for the Glock G19 Gen5 9mm, 7.2" for the Sig Sauer P365-Fuse 9mm) and within 0.53 oz in weight (23.63 oz vs 23.1 oz), which is why the Fuse gets pitched as a direct alternative. The specs separate on capacity, width and features: the Fuse holds 21+1 to the G19's 15+1, is 0.24" narrower (1.1" vs 1.34"), runs a longer 4.3" barrel vs 4.02", and lists a 0.5 lb lighter trigger at 5.3 lb vs 5.8 lb. The Fuse is optic-ready with a green fiber optic front sight; the standard Gen5 G19 is not cut and uses fixed sights. MSRP is $647 for the G19 and $799.99 for the Fuse.

Pick the Glock G19 Gen5 if:

• You want to spend $152.99 less at MSRP ($647 vs $799.99)
• You do not need a factory optic cut or 21-round magazines to be satisfied with 15+1
• You want the simpler fixed-sight, trigger-safety setup with three magazines included

Pick the Sig Sauer P365-Fuse if:

• You want six more rounds in the same footprint (21+1 vs 15+1)
• You want a 0.24" narrower gun against the body (1.1" vs 1.34")
• You want the optic cut, the fiber optic front sight and the lighter 5.3 lb trigger from the box

Size and weight are effectively tied. The choice is whether the Fuse's extra six rounds, narrower slide and optic cut are worth $152.99 more than the G19.
