So this came up in my feed. Don't know why, but what the heck is a p320? I gather it's some kind of gun but I hate that people post things assuming that everyone who sees it knows what they're talking about.
The P365 is a decent compact sidearm. The construction of the P320 is a completely different platform. The “uncommanded” discharges appear to be possibly related to MIM [Metal Injected Mold] parts made by an Indian company.
When I was in a small town in Arizona a few years back, the local liquor store also sold ammunition…from a drive through window. That’s not disturbing 😳
Truly a case of stupid is as stupid does if they know there’s a problem and still won’t stop carrying them. How about that AFB where the Sig went off in the holster? They made the security police carry M4s until they could get replacement handguns.
I don’t own a gun but I worked in and around a machine shop for precision instruments many workers were gun nuts, (Shotgun Digest in the mens room) Can it be smith’ed? I can’t believe there’s no video on youtube.

There’s (multiple) fixes available.
SIG P320 Voluntary Upgrade Program
Overview: Launched in August 2017, the SIG Sauer Voluntary Upgrade Program addresses safety concerns with the SIG P320, particularly the risk of unintentional discharges when dropped at specific angles (notably -30°). The program aims to enhance drop safety and reliability for pre-2017 P320 models, following reports of rare but serious incidents, including law enforcement injuries. SIG Sauer emphasizes that the program is not a recall, as the pistol meets industry safety standards, but an optional upgrade to improve performance.
Key Upgrades:
1. Trigger Mechanism: Replaces the original trigger with a lighter, slimmer design featuring a shorter pull and improved geometry to reduce the chance of unintended activation.
2. Sear and Striker: Installs a redesigned sear and striker to ensure the pistol remains drop-safe, addressing the issue where the striker could release under specific impact conditions.
3. Disconnect Notch: Adds a mechanical disconnector to prevent the striker from releasing unless the trigger is intentionally pulled.
4. Recoil Spring: Upgrades to a lighter recoil spring assembly to reduce stress on internal components and improve cycling reliability.
5. General Inspection: SIG performs a full inspection, cleaning, and testing to ensure the firearm meets updated specifications.
Eligibility:
• Applies to all P320 models manufactured before August 8, 2017 (serial numbers can be checked on SIG’s website).
• Includes civilian, law enforcement, and military P320 variants (except those already upgraded, like the M17/M18).
• Available to U.S. owners only; international owners must contact local SIG distributors.
2. Shipping: SIG provides a prepaid shipping label. Owners send the pistol (or just the fire control unit in some cases) to SIG’s facility in Newington, New Hampshire.
3. Turnaround: Upgrades typically take 4–6 weeks, though delays may occur during high demand. SIG covers all costs, including shipping.
4. Return: The upgraded pistol is returned with the new components installed, tested, and certified.
Additional Notes:
• No Cost: The program is free, including parts, labor, and shipping.
• Post-Upgrade Models: P320s manufactured after August 2017 (and all M17/M18 variants) already include these upgrades, marked by an “X” in the model name (e.g., P320 XCarry).
• Verification: Upgraded pistols may have a marking on the slide or frame indicating completion. Owners can confirm upgrade status via SIG’s customer service (1-603-610-3000).
• Impact on Lawsuits: Despite the program, some lawsuits claim the upgrades don’t fully address unintentional discharge risks in holstered scenarios, though SIG disputes this, citing user error or improper holsters.
Recommendations:
• Check your P320’s serial number on SIG’s website to confirm eligibility.
• If concerned about safety, participate in the program before carrying or using the firearm.
• Use only SIG-approved holsters post-upgrade to minimize risks.
• Contact SIG customer service for clarification or issues during the process.
The program has been widely utilized, with thousands of pistols upgraded, but owners should weigh ongoing litigation concerns and ensure proper handling/holstering practices. For further details, visit sigsauer.com/support/p320-voluntary-upgrade or contact SIG directly.
The SIG P320, a modular striker-fired pistol adopted by the U.S. military as the M17/M18, has faced scrutiny primarily for unintentional discharges (UDs), where the gun allegedly fires without a deliberate trigger pull. This has been reported in over 100 lawsuits and incidents, including injuries to law enforcement officers and civilians, often in holsters or during holstering. Investigations suggest potential causes include holster interference, design flaws in the trigger mechanism (lacking a traditional trigger safety), and the pistol’s fully cocked striker at rest, which may allow movement-induced firing. SIG Sauer maintains that UDs result from user error or external factors, not inherent defects, and denies any design flaw.
Secondary issues include:
• Drop safety failures (early models firing when dropped at specific angles).
• Trigger malfunctions (gritty pull, failure to reset, or light strikes).
• Feeding/ejection problems (failures to feed or eject casings, often due to dirt or misalignment).
• Assembly errors post-disassembly, leading to failures to fire.
These issues peaked around 2017–2020 but persist in reports as of 2025, with ongoing lawsuits and some agencies banning the pistol.
Potential Remedies
• Voluntary Upgrade Program: SIG offers a free upgrade for pre-2017 models, installing a lighter trigger, modified sear, and striker, plus a lighter recoil spring to enhance drop safety. Post-upgrade models (e.g., M17/M18) incorporate these changes. Owners can send guns to SIG for inspection/upgrade via their website.
• Cleaning and Maintenance: For trigger/feed/ejection issues, thoroughly clean with solvent and a brush; inspect/replace recoil springs, extractor, or slide stops. Ensure proper reassembly to avoid misalignment.
• Holster Selection: Use SIG-approved holsters to prevent debris or interference; avoid aftermarket ones not designed for the P320.
• Add-Ons: Install a manual safety (available on some variants) or aftermarket trigger guards for extra protection.
• Professional Inspection: Contact SIG customer service for diagnostics or replacements; many users report quick resolutions. For UDs, some recommend switching to competitors like Glock or S&W if concerns persist.
While reliable for many users, ongoing litigation highlights caution for carry use. Always follow safe handling practices.

The title includes Sig, one of the largest gun manufacturers in the business.

E.g., Ford F-250, Apple iPhone 16, SIG P320,…
Some of us do… took me less time to answer her, than you took not to (~3.7 seconds ~;-)
Fact check: mostly true ☑️
you lost me at “i went to my local gun shop”
I’m very happy with my little P365
I still have all my toes…
The P365 is a decent compact sidearm. The construction of the P320 is a completely different platform. The “uncommanded” discharges appear to be possibly related to MIM [Metal Injected Mold] parts made by an Indian company.
buUut… does everyone standing nearby?
(Just kidding… not the same weapon ~;-)
One thing disturbing to me, as an Australian: “…my local gun shop…”
When I was in a small town in Arizona a few years back, the local liquor store also sold ammunition…from a drive through window. That’s not disturbing 😳
Here’s the opposite, and less lethal: When I lived in Denver a few years back, there was a Taco Bell next door to a cannabis dispensary!
I love that! I wonder which opened first?
Head to Iowa, where blind people can own firearms. Wonder how many other states permit this.

You win today’s craziest fact. Maybe we should accuse them of being woke, of pandering to DEI? 😁
Yeah, he made ‘my local gun shop’ sound like he was going to Sainsbury’s for a pint of milk, and half a dozen eggs!
"Hon, I'm steppin' out for some beer and hollow points. Back soon."
That blew my mind too. It really is a backward nation
Truly a case of stupid is as stupid does if they know there’s a problem and still won’t stop carrying them. How about that AFB where the Sig went off in the holster? They made the security police carry M4s until they could get replacement handguns.
I'd sooner trust a baseball bat.
Is the military still using
But curiously if this is alledgedly true?
Court Records Reveal Sig Sauer Knew of Pistol Risks for Years - The Smoking Gun | The Smoking Gun https://share.google/H6VdDWWx2Dqyks7yd
So I take it this is a major problem that the manufacturer is blissfully unaware of?
I don’t own a gun but I worked in and around a machine shop for precision instruments many workers were gun nuts, (Shotgun Digest in the mens room) Can it be smith’ed? I can’t believe there’s no video on youtube.
Keep it unchambered.
DUUUUUHHHHHHHHHH
Designed by indians for pennies on the dollar. Outsourced..
Does the P365 have the same issue?
Maybe don’t leave a round chambered… duh?
Maybe learn that's a good way to get killed. What a stupid statement on your part. You clearly know nothing about carrying for self defense.
