FN Reflex MRD 9mm vs Sig Sauer P365 9mm

The FN Reflex MRD 9mm is hammer-fired with an internal single-action mechanism; the Sig Sauer P365 9mm is striker-fired. That shows in the trigger, 4.5 lb against 5.5 lb. The Reflex holds one more round (11+1 vs 10+1), is 0.06" narrower (1.0" vs 1.06") and 0.03" shorter in height (4.27" vs 4.3"), but is 0.4" longer overall (6.2" vs 5.8") and 0.6 oz heavier (18.4 oz vs 17.8 oz). It runs a 3.3" barrel to the P365's 3.1", a 5.05" sight radius to 4.9", and a factory optic cut this P365 does not have. The P365 ships with XRAY3 day/night sights front and rear. MSRP is $676 against $519.99.

Pick the FN Reflex MRD if:

• You want the 1 lb lighter pull, 4.5 lb against 5.5 lb, from the internal hammer-fired action
• You want a factory optic cut without moving to a different model
• The 1.0" width and 11+1 capacity fit your carry better

Pick the Sig Sauer P365 if:

• You want the shorter gun at 5.8" overall, 0.4" less than the Reflex
• $519.99 against $676 — $156.01 less
• XRAY3 day/night sights front and rear come in the box

Weight and width are within 0.6 oz and 0.06", so size is nearly a wash. The split is the Reflex's hammer-fired trigger, extra round and optic cut against the P365's shorter frame, night sights and $156.01.
