Owners of the XP Pro frequently point to the Glock magazine compatibility as the primary reason they chose it over other 9mm options. Having access to a large existing aftermarket for magazines is practical, and most find this feature works reliably across a range of Glock-pattern magazines.

The included RMR plate gets attention from buyers who want a ready-to-optic setup from the start. Those who run a dot on it report a straightforward mounting experience, though opinions on the optic height and co-witness position vary between users.

Build quality draws mixed responses overall. Some owners run the XP Pro without issues and consider the value solid for the price point. Others note that fit of certain components is looser than expected and recommend a proper break-in period with quality ammunition before passing judgment on long-term reliability.
