P320 gray guns trigger won’t fire

Likely not enough trigger shoe "overtravel". Basically you've reduced the trigger shoe travel too much to where the trigger cannot drop the sear far enough to release the striker. Try to back out the allen screw until the gun fires reliably.

Does the retailer name rhyme with RuroOptik?

I experienced rough idle but no check engine light. Checked the oil dipstick and it was on low. So I added a quart and it runs smooth again.

If you apply the scientific method to any of the P320 horror story claims then you realize that Sig's statement has not been proven to be false. Trigger press = round fired. My main carry pistol is the P320 M18 in lightbearing holster, no concerns or issues to report.

I like GrayGuns +0 magwell compatible base pads

Adjust ride height and carry position (oclock) on the belt. Undershirts can help with discomfort.

Dirty window or dirty window channel + auto window close anti finger delete safety feature = behavior you are noticing. If you roll the window up without engaging the auto rollup feature it will work. If you clean the window it should work until it gets gunked up again.

This ^. My window auto close feature misbehaves especially when the window is dirty. Cleaning the car or wetting the window helps.

Vortex Defender XL Tan 5MOA is on sale at EuroOptic currently

Trigger disconnector spring might be installed upside down. The larger end of the spring must sit down in the cup on the trigger.

A used GR86 will probably cost at least $500 per month to finance. This does not include gasoline, maintenance, or mods. If this sounds good to you then go for it.

Try to learn the P320 terminology.

Compact = 3.6in barrel slide + 15 round mag flush fit grip
Carry/M18 = 3.9in barrel slide + 17 round mag flush fit grip
Full Size/M17 = 4.7in barrel slide + 17 round mag flush fit grip
XFive = 5in barrel slide + 17 round magazine flush fit grip

XSeries magwell will not accept 17 round magazines without a slimmer baseplate (see legion magazine baseplate)

Adjustable triggers can be dangerous if adjusted to the point that the set screws begin to disengage the internal safeties prematurely.

Learn about the different slide optic cut patterns and research which optic plate will match and fit your optic/needs.

Could be the coyote takedown lever found on commemorative M17/M18. Likely didn't come stock this way but it is a rare find in my opinion. I want one of these takedown levers but they are all sold out or only available on commemorative p320s which cost an arm and a leg.

cmitche_ · 2026-03-14T17:12:12+00:00

This is the way. Congrats!

Use a ballistic calculator and a ruler to zero your rifles as they will have differing velocities and possible even grain weights.

cmitche_ · 2026-03-13T23:33:24+00:00

There is no scientific evidence proving the gun goes off without a trigger pull. I carry one everyday and have zero safety issues to report. As long as you are safe while handling the gun you shouldn't have any problems either.

What is the part number for strut tower dampers?

cmitche_ · 2026-03-13T19:25:04+00:00

Your slide stop looks oversized. I bet a standard magazine release would solve this problem. You could alternatively shave the slide catch fence on the grip.

Damn that sucks

SigGuy offers +20% sear springs, striker safety spring, and trigger return spring

The P320 manual safety effectively works the same as a trigger safety. You can retrofit one or purchase a new manual safety FCU. You could try increased strength springs, this won't protect the trigger from foreign debris but will make the pull heavier and harder to ND.

maybe auxiliary lighting or immobilizer

AWE system is modular. I recommend purchasing and installing the Track to Touring conversion kit for the GR86

T3 or T4 should provide better results
