SIG Sauer P320 Compact .45 ACP | Factory Night Sights, Custom Stippled Grip, 3 × 9-Round Mags
The P320 Compact chambered in .45 ACP is no longer in active production, making this modular striker-fired pistol an attractive find for shooters who want full-house .45 power in a carry-sized frame. This example adds professionally executed aggressive stippling on the grip module for enhanced control and retains its factory SIGLITE tritium night sights, three magazines, and the proven stainless-steel/Nitron slide and barrel combination.
Condition
Overall Condition: Very good condition, showing only light, superficial signs of prior handling or use.
Bore Condition: Excellent - Clean, mirror finish, no signs of wear.
Bore Rifling: Excellent Rifling - Sharp lands and grooves.
Specific Condition Notes: The grip module’s aftermarket stippling is crisp and even, with only minimal finish wear on high-contact edges of the slide.
What’s Included
- Three 9-round steel factory magazines marked "Made in Italy" (OEM Mec-Gar)
The factory-machined slide wears a black Nitron finish and sports both front and rear serrations plus a loaded-chamber view cut, giving quick purchase and visual status at a glance. SIGLITE 3-dot tritium sights deliver a bright, low-light sight picture without relying on batteries.
Aggressive stippling on the polymer grip module replaces the original texture, locking the pistol into the hand during rapid strings while maintaining the P320’s fully modular design. The serialized fire control unit can still be swapped into other P320 grip sizes or calibers without additional paperwork.
Controls remain ambidextrous or reversible where applicable: the slide-catch lever mirrors on both sides and the magazine release can be switched for left-hand use. Inside, the stainless 3.9-inch barrel teams with a locked-breech, striker-fired action for consistent ignition and reduced muzzle rise.
Although discontinued, the Compact .45 variant retains full parts compatibility with the broader P320 ecosystem, but complete pistols have become harder to source—especially with factory night sights and extra magazines included.
