VP9A1 F owners frequently praise the trigger as one of the better striker-fired pulls available, citing a clean break and consistent reset. The full-size frame and 4.53-inch barrel get credit for easy control during extended range sessions. The ambidextrous controls draw particular praise from left-handed shooters.

The interchangeable backstrap grip system is appreciated by shooters with larger or smaller hands, though some find the grip panels slightly bulky compared to other full-size pistols. The optic-ready slide is a practical addition, and inclusion of both 17-round and 20-round magazines is frequently cited as good value out of the box.

The VP9A1 F draws occasional criticism for its price relative to domestic competitors in the full-size category. The Picatinny rail is seen as a positive for light and laser attachment, though a minority of buyers find the polymer frame finish less refined than metal-framed alternatives.
