Frequently Asked Questions
Is the rainbow finish durable?
Yes. The finish is a Physical Vapor Deposition (PVD) coating, which is highly resistant to wear, corrosion, and holster abrasion. It’s far more durable than traditional cerakote or anodizing.
How does it compare to the 9mm P365?
The primary difference is the chambering. The .380 ACP version offers significantly less felt recoil, making it easier to shoot, especially for newer shooters or those with sensitivity to snap. Our staff has also noted the tolerances on this model are noticeably tighter than the previous generation.
What optics fit the slide cut?
The slide is cut for the SIG Sauer ROMEOZero Elite footprint. This pattern also directly accepts the Shield RMSc and similar micro red dots. Adapter plates are available for other optics like the Holosun EPS Carry.
