FN specifies the trigger pull as 5.5 to 7.5 pounds. It felt more like the 8-pound range to me, but we always weigh the triggers anyway. This one turned out to average 8.85 pounds when weighed at the center, where the shooter’s trigger finger generally lies. Measured at the toe, the bottom tip of the trigger, the Lyman digital gauge from Brownell’s registered an average of 6.5 pounds, right in the middle of FN’s stated range. I suspect the factory (like most) took the measurement low on the trigger, where greater leverage requires less pressure.

There’s more to trigger pull-quality than weight, of course. There’s pace, and perhaps most important, smoothness. Our test 509, serial number GKS0001514, exhibited “creep” as noted by all on the test team. That is, as the trigger began coming back, it transmitted little “catches” to the trigger finger as the internal parts moved against each other. This was less noticeable in rapid fire. There was also palpable backlash, or additional rearward movement of the trigger after the sear released. In between that draggy take-up and the shot, the pull “at the wall” (i.e., just before discharge) felt about like a Glock with an 8-pound connector. Some FN 509 owners have reported excellent triggers, so sample GKS0001514 may have simply been an exception.
