Icarus Precision has introduced the ACE 365 EVO series of SIG P365 grip modules. The new EVO series currently includes two grip modules – ACE 365 XL EVO and ACE 365 PMM EVO. The XL EVO grip module has a dust cover flush fitting the length of a SIG P365 XL slide. The PMM EVO is designed to fit flush an XL length slide and PMM Gen 2 Micro JTTC compensator combo.
