Glock G43X 9mm vs Sig Sauer P365 9mm

Both are slim 9mm carry pistols at 10+1. The G43X has a 0.74" taller grip (5.04" vs 4.3"), runs a 0.31" longer barrel, and stretches 0.7" longer overall. Width and weight are within thresholds, so on the belt these feel similar — the difference is grip length. The longer G43X grip gives a full-finger hold; the shorter P365 grip clears under a tucked shirt where the G43X will print.

Pick the Glock G43X if:

• You want a full-finger grip at 5.04" tall — the P365's 4.3" forces a pinky-tuck for most hands
• You want the Glock manual of arms and aftermarket if you already shoot a G19 or G17
• You want a 3.41" barrel and 5.24" sight radius for slightly better recoil control and aim radius

Pick the Sig Sauer P365 if:

• You want a 0.74" shorter grip for pocket or inside-the-waistband carry where any grip drop prints
• You want a 0.7" shorter overall length for the smallest concealment footprint
• You want a serialized modular FCU that swaps into P365 X, XL, and X-Macro grip modules

Both are striker-fired polymer 9mms at 10+1. The G43X is built for shooters who want a full grip in a slim package; the P365 sacrifices grip length to be smaller.
