Owners of the Panzer Arms ARP9 generally appreciate the AR-9 pistol format at its price point. The 9mm chambering is easy on ammo costs, and the 33-round magazine capacity means less time reloading at the range. Most owners treat it as a fun plinking firearm.

The ARP9 gets mixed marks on fit and finish. Some owners find the build quality acceptable for the price; others note that tolerances are looser than higher-end AR-9 pistols and that the factory trigger feels gritty. Running higher-quality brass ammunition is a common recommendation from owners who experienced reliability hiccups.

The Blue/Black finish has decent reception among those who wanted a distinctive look. The platform is not widely supported by aftermarket accessory makers at the level of name-brand AR-9s, which is a noted limitation for buyers who want to customize heavily.
