Frequently Asked Questions
Sig Sauer P320 Compact for sale
Is the Sig Sauer P320 Compact a good gun?
Whether it's good depends on your needs. The P320 Compact is reliable, accurate, and widely adopted by law enforcement. It handles concealed carry and range use well. Priced around $550, it offers solid performance for defense or training, though some users note its grip size falls between compact and full-size.
Are P320s safe now?
The 2017 voluntary upgrade addressed drop-safety concerns, but debate continues. Some users and ongoing lawsuits report unintended discharges even in upgraded pistols. Other sources consider it as safe as comparable striker-fired pistols, though potentially less forgiving of unsafe handling. Use a quality holster covering the trigger guard and follow safe handling practices.
What is the difference between Sig P320 and P320 compact?
The full-size P320 has a longer slide, barrel, and grip module holding 17 rounds, while the compact has a shorter slide, barrel, and grip holding 15 rounds. Both share the same modular action. The compact's reduced size makes it better suited for concealed carry; the full-size offers greater capacity.
What is the best holster for the P320 compact?
Best holster depends on your carry method. For concealed carry, IWB options like Vedder LightTuck or Bravo Concealment are popular choices. For open carry or range use, OWB paddle holsters offer quick access. Ensure any holster fully covers the trigger guard and fits your carry style and comfort needs.
Is the P320 compact good for concealed carry?
Yes. The P320 Compact works well for concealed carry, though it was not designed specifically for that purpose. Its shorter slide and grip reduce size and weight versus the full-size model. Some users find it wide, so fit depends on body type and holster choice. Typically priced around $550.
Does SIG make a P320 in 45 ACP?
Yes, SIG does make the P320 in .45 ACP. Options include a compact version with a 3.9-inch barrel and SIGLITE night sights, and a full-size version with a 4.7-inch barrel. The P320 is also available in 9mm, .357 SIG, and .40 S&W.
What magazines fit the SIG P320 compact?
SIG P320 Compact accepts 15-round magazines in 9mm, 10-round in .40 S&W, and 9-round in .45 ACP. These are also compatible with the P250, and larger full-size magazines can work in the compact frame. Confirm caliber and designation when ordering from our marketplace.
Does SIG P320 have a threaded barrel?
SIG doesn't ship P320s with threaded barrels from the factory, but aftermarket threaded barrel replacements are available. Full-size models typically accept 1/2x28 threaded barrels. Check your local laws, as some states restrict threaded barrels.
