Last updated October 2026 · By Nick Hall, tracks California carry-permit policy and Second Amendment litigation for USA Gun Shop readers
Quick take: The Second Amendment Foundation says the Contra Costa County Sheriff has agreed to stop banning red dot sights, weapon lights and 1911 and 2011 pistols on concealed carry permits. SAF dropped its federal lawsuit a day later, on October 9, 2026. The sheriff’s own CCW page still listed all three bans when I checked it on October 11, so hold off on changing your carry gun.
- What happened: SAF announced a settlement on October 8, 2026, and the plaintiffs filed a notice of voluntary dismissal in Moore v. Contra Costa County, case 4:26-cv-05996 in the Northern District of California, on October 9.
- Why it matters: The sheriff’s published rules bar any single-action-only firearm, 1911-pattern pistols included, and any carry gun with an attached red dot or flashlight.
- What’s next: SAF says the office will update its concealed-carry website within 10 days, and the old rules were still posted on October 11, 2026.
- Who to watch: Sheriff David Livingston, whose office had posted no press release about the deal as of October 11.
Most California carry-permit fights are about money or waiting time. This one was about hardware. One sheriff was telling licensed carriers they couldn’t use sights, lights and pistols that, according to the complaint, several California police agencies have adopted as duty guns. I read the complaint, the docket, SAF’s release and the sheriff’s permit page, and the four don’t line up yet.

What the Contra Costa CCW Page Says Today
The rules at issue aren’t in a statute or a county ordinance. They sit in Step Five of the Office of the Sheriff’s Apply for a CCW Permit page, under a heading that reads WEAPONS.
The pistol rule is two sentences long. “Prohibited firearms include any single action only firearms.” Then: “This includes any semi-automatic handgun made by any manufacturer built on the Colt 1911 configuration.”
The accessory rule is one. “Firearms with attached laser sights, flashlights, red dots, and sighting systems are not acceptable.” A few lines down the page repeats itself: “Add on optics are not permitted.”
That wording was on the page in an archived copy dated June 8, 2026, nine days before the lawsuit. It was still there, word for word, when I loaded the live page on October 11, 2026.
The page also caps a permit at two guns, limits caliber to no less than .32 and no more than .45, and has a Range Master inspect each gun at qualification. It routes residents of 13 cities, Concord, Richmond and Walnut Creek among them, to separate application links and tells everyone else to apply through the Office of the Sheriff.
What SAF Was Alleging in Moore v. Contra Costa County
The complaint, filed June 17, 2026 in the Oakland Division by SAF and two county residents, Andrew Moore and James Treuel, named Contra Costa County, the Sheriff’s Office and Sheriff David Livingston in his official capacity, and it brought a single claim under the Second and Fourteenth Amendments.
Both men already hold Contra Costa permits. Moore’s lists a Sig Sauer P365 Legion and a Smith and Wesson, and Treuel’s lists a Sig Sauer P365 and an HK USP Compact. The complaint says each man “has refrained from attaching these items to his CCW firearms” out of fear of prosecution or losing the permit.
The sharpest point in the filing is about who the rule missed. Because California permits are valid statewide, the complaint says, people licensed by other counties “can legally carry firearms with red dot sights and/or flashlights when visiting or passing through Contra Costa County.” Residents could not.
It also flags a catch for anyone who owns a Heckler & Koch VP9F SCS, a roster pistol that ships with a Holosun optic installed. Carry it as sold and it has a red dot. Take the dot off and it has been modified, which the sheriff’s page also forbids.
The suit asked for a declaratory judgment, an injunction, nominal damages and attorney’s fees. It was narrow by design. Two footnotes say the plaintiffs were not challenging the county’s limits on derringers, laser sights, modified triggers or single-action revolvers.
What SAF Says the Sheriff Agreed To
Everything in this section comes from one side. SAF’s October 8, 2026 release says the Sheriff’s Office “will withdraw its prohibitions on red-dot sights, weapon-mounted lights and semiautomatic single-action 1911 and 2011 platform pistols carried under a county CCW license.”
SAF adds two conditions. Applicants still have to pass the usual range qualification with any gun they list, and existing licensees who add a dot or a light “may also be required to present the firearm for inspection and to qualify with the added accessory.”
“A sheriff does not get to invent a shorter list of approved handguns and accessories than the Constitution allows,” said Kostas Moros, SAF’s Director of Legal Research and Education and an attorney of record in the case. Executive Director Adam Kraut called it “a practical win for people who already have, or are seeking, a Contra Costa carry license.”
The sheriff’s page never uses the word 2011. It doesn’t need to, because a 2011 is a double-stack 1911 with the same single-action trigger, and the ban is written around the trigger.
SAF’s release does not link the agreement, and no settlement document is on the docket. The sheriff’s press release page shows nothing newer than August 18, 2026. And SAF’s list stops at three items, so laser sights, derringers and the modified-gun rule are not part of what it says changed.
What the Dismissal Is, and What It Is Not
The docket shows entry 13, a “NOTICE of Voluntary Dismissal by Andrew Moore, Second Amendment Foundation (SAF), Inc., James Treuel” filed on October 9, 2026. The plaintiffs ended the case themselves. No judge ordered it.
The docket has 13 numbered entries, and none of them is an answer from the county or a ruling on the policy. Judge Jon S. Tigar took the case by reassignment on July 6, 2026 and had a first case management conference set for October 27. It never got that far.
The entry does not say whether the dismissal is with or without prejudice. The default under Federal Rule of Civil Procedure 41 is that a dismissal by notice is without prejudice unless the notice says otherwise.
So there is no injunction, no consent decree and no finding that the bans were unconstitutional. Nothing here binds another sheriff or police chief. One county. One office.
State law is untouched too, and the complaint said outright that it brought no claim under California law. Penal Code section 26200 still bars carrying a firearm not listed on the license and caps a licensee at two guns at a time, and section 26230 still lists the places a permit holder can’t carry. Our California gun laws guide covers the rest.
What Contra Costa Permit Holders Should Do Now
Nothing yet. The posted rules are what a Range Master will read at qualification, and the page is blunt about the penalty: “Any modifications to firearms after issuance of a permit may result in revocation.”
But the fix should be quick if SAF has the terms right. The page lists a CCW Coordinator at (925) 655-0059, and a changed web page or an answer in writing is worth more than a press release from the other side.
Adding a 1911 is a separate job from bolting on a dot. The page requires a state modification form, BOF 4502, for any firearm change, and says you will have to qualify with the new gun.
If you have been waiting to put a carry-sized red dot on a listed pistol, wait a little longer. If the page changes inside SAF’s 10 days, county carriers got what the lawsuit asked for without a single hearing. If it doesn’t, the case that forced the issue is already closed.
The lawsuit is over. The web page hasn’t caught up.
Frequently Asked Questions
Can I carry a red dot on my CCW gun in Contra Costa County?
The Second Amendment Foundation says the Contra Costa County Sheriff agreed in October 2026 to withdraw the ban on red dot sights for guns carried under a county CCW license. As of October 11, 2026 the sheriff's permit page still said firearms with attached red dots are not acceptable. Check the page or call the CCW Coordinator before you change a listed gun.
Are 1911 and 2011 pistols allowed on a Contra Costa CCW permit?
SAF says the sheriff agreed to withdraw the ban on semiautomatic single-action 1911 and 2011 pistols. The sheriff's page, as it read on October 11, 2026, still listed any single action only firearm as prohibited, including any semi-automatic handgun built on the Colt 1911 configuration. Adding one to a permit also takes a state BOF 4502 modification form and a qualification with the new gun.
What was Moore v. Contra Costa County?
It was a federal lawsuit, case 4:26-cv-05996 in the Northern District of California, filed June 17, 2026 by the Second Amendment Foundation and county residents Andrew Moore and James Treuel. It challenged the sheriff's bans on red dot sights, weapon-mounted lights and single-action 1911-style pistols for carry permit holders. The plaintiffs filed a notice of voluntary dismissal on October 9, 2026.
Did a court rule the Contra Costa CCW restrictions unconstitutional?
No. The case ended with a voluntary dismissal filed by the plaintiffs, before the county filed an answer and before any ruling on the policy. There is no injunction, no consent decree and no court finding on whether the restrictions violated the Second Amendment.
Does the Contra Costa settlement apply to other California counties?
No. It concerns one sheriff's office and the permits it issues. The complaint itself said that, to the plaintiffs' knowledge, no other county or city in California restricted red dot sights, flashlights or single-action pistols on carry permits.
Do I have to requalify if I add a red dot or weapon light to a listed carry gun?
You may. SAF's release says existing licensees who add a red dot sight or weapon-mounted light to a listed firearm may be required to present the firearm for inspection and to qualify with the added accessory. New applicants still have to pass the range qualification with any gun they list.
Are laser sights now allowed on a Contra Costa CCW gun?
Nothing says so. The sheriff's page bans attached laser sights in the same sentence as flashlights and red dots, but the lawsuit did not challenge the laser rule and SAF's release lists only red dot sights, weapon-mounted lights and 1911 and 2011 pistols. The county's limits on derringers and modified guns were not part of the suit either.
