Owners of the PDP F-Series Pro consistently praise the trigger. The reset is short and the break is clean, which makes it a frequent comparison point when people are evaluating striker-fired pistols in this size class. The bundled Aimpoint ACRO P-2 optic is seen as a genuine value addition rather than a placeholder sight.

The grip texture and interchangeable backstraps are well received, particularly by shooters with smaller hands who find the F-Series grip shape more comfortable than a standard PDP. A handful of owners note the pistol is slightly heavier than expected with the optic mounted, which affects how it sits in some holsters designed for the base PDP.

The 18+1 capacity and three included magazines get positive marks for out-of-box readiness. The common criticism centers on holster availability: dedicated fits for the F-Series Pro with optic are more limited than for the standard PDP, so some owners end up ordering custom or universal solutions.
