Key Features
- Optic-Ready Slide – The slide is cut to the Sig-Loc footprint, so you can mount a micro red-dot directly without plates. This means faster target acquisition and a clearer sight picture for new shooters.
- XRAY3 Day/Night Sights – Tritium front and rear sights glow in low light, giving you a reliable aiming point even when the sun goes down. Perfect for home defense or evening range sessions.
- Ambidextrous Manual Safety – A thumb safety on both sides of the frame makes this pistol suitable for left- and right-handed shooters. It adds an extra layer of security for families teaching new shooters.
- Mechanical Loaded-Chamber Indicator – A small tab pops up when a round is chambered, giving you a visual and tactile confirmation. This helps prevent accidental discharges, especially for beginners.
- Magazine Disconnect – The pistol won’t fire if the magazine is removed, even if a round is in the chamber. This is a safety feature that many trainers recommend for new shooters.
Who It’s For
This pistol is for families and new shooters who want a reliable, easy-to-handle concealed carry gun. The manual safety and loaded-chamber indicator make it a great choice for teaching safe handling. It’s also ideal for youth shooters moving up from a .22, thanks to the manageable 9mm recoil and compact grip.
Pros & Cons
- Pros: Compact enough for deep concealment, optic-ready without extra plates, excellent night sights, ambidextrous safety for lefties, magazine disconnect for extra safety.
- Cons: The Sig-Loc footprint is proprietary, so you’re limited to SIG SAUER optics or adapters. The grip texture can be a bit aggressive for some shooters – a simple grip sleeve or Talon tape solves that.

FAQ
What optics fit the Sig-Loc footprint?
The Sig-Loc footprint is designed for SIG SAUER’s ROMEOZero and ROMEOZero Elite micro red dots. Some third-party optics may work with adapters, but for a direct fit, stick with SIG SAUER optics.
Can I remove the manual safety?
Yes, the safety can be removed by a qualified gunsmith, but we recommend keeping it on for new shooters. It’s easy to disengage with your thumb during the draw.
Is the magazine disconnect removable?
Per SIG SAUER specs, the magazine disconnect is not user-serviceable. Removing it may void the warranty. We suggest leaving it in place for safety.
What holsters fit this model?
Most P365 holsters will work, but check that the holster is molded for the manual safety version. Brands like Vedder, Alien Gear, and CrossBreed offer compatible options.
What is the trigger pull weight?
Per manufacturer specs, the trigger pull is approximately 5.5 to 6.5 pounds. It’s a smooth, consistent pull suitable for beginners and experienced shooters alike.
