Owners of the P320 Carry in .45 ACP generally praise the trigger and the modular design, which lets them move the fire control unit into different grip modules without re-serializing. The factory night sights draw consistent positive comments as a practical out-of-the-box feature.

Carry ergonomics get mixed marks. Some find the carry-size grip comfortable for all-day use, while others feel the .45 ACP configuration runs a bit thick compared to 9mm variants. Recoil in .45 ACP from the 3.9-inch barrel is described as manageable but more noticeable than the smaller-caliber P320s.

The Nitron finish holds up reasonably well under daily carry, though some owners report minor wear at holster contact points after extended use. The 10+1 capacity is acceptable for the caliber, but splits opinion among those who prioritize round count.
