Frequently Asked Questions
Sig Sauer P320c for sale
What is a SIG P320C?
The SIG P320C is the compact variant of SIG Sauer's modular, striker-fired pistol line. Introduced in 2014, it features a polymer frame, M1913 accessory rail, and consistent trigger pull. Designed for concealed carry, it retails around $630 and remains in current production.
Is the Sig P320 compact a good gun?
Most reviewers consider it reliable, accurate, and well-suited for concealed carry or daily defense. Its modular design lets you swap frames and slides without an FFL transfer. Priced around $630, it compares favorably to competitors like the Glock 19.
Is the SIG P320C safe?
The SIG P320C meets military and law enforcement safety standards worldwide. Like all striker-fired pistols, safe handling is essential: maintain proper grip, keep your finger off the trigger until ready to shoot, and store it securely. No mechanical safety replaces responsible handling.
Is it safe to carry a SIG P320 with a round in the chamber?
Yes. The P320 has a firing pin block safety and no external hammer, making it safe to carry chambered. Use a quality holster that fully covers the trigger guard, keep your finger off the trigger until ready to shoot, and the gun will not fire unless the trigger is deliberately pressed.
What mags will fit in a SIG P320?
SIG P320 magazines are interchangeable across 9mm variants. Factory options include 15-round compact and 21-round extended magazines. Magpul PMAG 21 GL9 also fits. Larger-frame mags work with a sleeve adapter. Always verify compatibility with your specific grip module size.
What are the key differences between the Sig Sauer P320 and P320c?
The P320 Compact has a shorter grip module than the P320 Carry, reducing height and magazine capacity from 17 to 15 rounds. Both share the same slide length and chamber 9mm. The Compact is better suited for concealed carry, while the Carry offers slightly more capacity.
How much should I pay for a P320?
SIG P320 pistols vary widely in price depending on model and condition. New guns currently average around $741, while used examples often sell in the $350–$450 range. Individual listings can go lower or higher. Check our marketplace for real-time availability and current deals.
Is the Sig Sauer P320 9mm discontinued?
No, the Sig Sauer P320 9mm remains in production. SIG implemented a voluntary upgrade program addressing trigger design, but the pistol continues to be manufactured and sold, with multiple variants available through various retailers.
What is the difference between the p320c and the M18?
P320 Compact uses a smaller grip frame holding 15 rounds, while the M18 uses a carry-size frame with 17-round capacity. The M18 includes an optics cut, ships with three magazines, and has a manual safety. Both are 9mm striker-fired pistols sharing the same basic platform.
What are common P320 problems?
Early P320s had a drop-safety issue where the pistol could discharge if struck at certain angles. SIG issued a voluntary upgrade in 2017, but uncommanded discharge reports have continued in properly maintained guns, leading some agencies to suspend P320 use. Users also report trigger reset inconsistencies and occasional feeding failures.
