## What Customers Say

*AI-generated insights from customer reviews*

The FN 510 MRD in FDE generates a fairly consistent pattern of feedback. Build quality and reliable operation are the leading positives. The pistol functions well across different 10mm load weights, which is notable given how much 10mm ammunition varies in pressure.

The optics-ready slide is the feature owners mention most positively. Being able to mount a red dot without additional machining is convenient, and the co-witness iron sights provide a usable backup. The grip texture and ergonomics draw good marks; most shooters find it comfortable to hold.

The criticisms cluster around size and price. The FN 510 is larger and heavier than many pistols in the category, which rules it out for concealed carry for most people. Aftermarket holsters and accessories are less widely available compared to platforms with a longer market history. The price also runs higher than some 10mm competitors, which draws scrutiny from budget-conscious buyers. Recoil with full-power 10mm is noticeable, not unusual for the caliber, but worth knowing for newer shooters.
