500 Rounds with the Newest FN 5.7
FN recently debuted the third generation of its 5.7x28mm caliber pistol, bringing the curious pistol from the 1990s kicking and screaming into a more modern period.
I’ve been testing for the past few months and have a 500-round review.
What the new MRD MK3 brings to the game is the ability to mount just about any micro red dot optic (hence “MRD”), something that was particularly hard to retrofit on previous models, as well as a lot of updates to the pistol’s ergonomics. All this in a hammer-fired delayed blowback action semi-auto with a semi-fixed barrel chambered for the spicy little 5.7 round.
