Owners drawn to the P365 DH3 are typically after the integrated compensator on a carry-sized pistol, and most report that the comp makes a noticeable difference in keeping the dot on target during fast follow-ups compared to a standard P365. The Romeo-X red dot in SIG-LOC format is generally well-received for its low-profile mount that keeps the pistol from printing too thick.

The Coyote Cerakote finish gets positive marks for durability, though some owners note that the lighter color shows holster wear faster than a matte black finish. The X-RAY3 backup sights are a frequently mentioned plus for those who want a co-witness option if the optic battery dies.

Capacity opinions vary. Those coming from a standard compact pistol are impressed by the 21-round option, but daily carry users often prefer to run the 17-round magazine for a more manageable profile. The DH3 package pricing draws mixed takes, with some calling the optic and magazine bundle a fair deal and others preferring to configure the pistol themselves.
