Sig P320 Fire Control Group Cleaning

[halfmoonclip]

GJM, that is indeed interesting. I've been in the habit of a dab of grease on that spot in Glocks, so I'll rethink things re: the Sigs.
Have to wonder; one of those levers is also the firing pin safety on the P320; wonder if they're concerned about that getting gunked up.
The P365, of course, has the Glock-like plunger in the slide.
Thnx,

My preferred method is:
Remove FCU
Blast with compressed air.
Spray it down with WD-40 and Let is soak for a minute or two.
Blast with compressed air.
Soak it down in isopropyl alcohol.
Blast with compressed air.
Pop it in the grip, and oil and grease the appropriate areas.

After a two day pistol class and 1,000 rounds through my P320c (it did awesome, BTW), I wanted to do a thorough cleaning of the FCU. I took it out, sprayed slip2000’s 725 cleaner all over it, and let it soak while I cleaned the rest of the gun. Then I (carefully) rinsed the FCU with hot water to wash away the 725 and accompanying crud, then used by wife’s hair dryer to heat it up (evaporate the water). I then got it nice and wet with slip2000 gun lube, and again used the hair dryer to blow the lube into crevices. Lastly, I wiped it completely dry (and used the dryer to push out any excess lube as I wiped it all dry).

Afterwards, it was cleaner than when I bought it new, all the parts (even dry to the touch) were lubed and protected, and it took all of 6 minutes. A huge plus to the chassis system.

Getting the take down lever out is the worst part of the deal; a drop of oil on the 0-ring makes the process much easier.
What is the expected life of the O-ring, he wondered.

Thnx, tho' not yet. I've got two 320s, and I may scrounge up some spares, so as not to take too big a hit on shipping.
Ordered an extra mag release directly from Sig, so as not to have to move one when swapping grip modules. Part was $9; so was the shipping....

Yeah, it just depends. Some modules have them, others not.
