Steved13,

I only have one question - how dirty was the gun after your range time? I have to admit I do clean the barrel and wipe things down after a session but I've not noticed much, if any crud after 200 rounds. I normally run a Rem oil patch through the barrel until it comes out clean, dry the barrel and lightly coat it inside and out because I never know when I'll be able to get out again.

Suggest you take at look at this post: http://http://sigtalk.com/p250-p320-modular-pistols/49054-factory-maintenance-lubrication-specs-p320-pistols.html

I take out the FCU and clean it after each range session. It doesn't get nearly as dirty as the barrel and slide assembly, though, so it doesn't take as much effort to clean it. I'll put on a very thin layer of oil every few cleanins - Mil-Comm MC 2500 - wipe on, let it sit a few minutes and then wipe of with a clean patch leaving a very thin layer (like you, I don't like to leave too much lube in there).

I will remove the FCU from the frame each time I clean, but I may not take it completely down each time. It depends on how much shooting I did that day.

I was a big TW25 and MC2500 user and had been using the stuff for years. Use the oil on the barrel, lug surfaces, and slide, and TW25 for the slide rails, trigger pivot points, and trigger bar assemblies. I recently switched to Slip 2000 oil and grease as it is quite a bit thicker than the Mil-Com stuff, and work a bit better with the 320's FCU mechanicals. The trigger is smoother with the Slip product compared to the Mil-Com, at least IMO.

This video pretty much lays it out from Sig's professional shooter. Not sure if this is the same as Abberdog posted as that link would not open for me. In general, he cleans incredibly infrequently, and I have heard the same from many successful benchrest shooters. I always tended to be on the compulsive side, but plan to clean my 320s as he suggests.

Do you pull the trigger out, to lube the pivot points, or just lube what you can and leave it in?

Now that I think about it, Everything I've seen says just give it the once over, and nothing about pulling the trigger or trigger bar and such. My OCD id just getting the better of me I think.

I've never broken down the FCU for cleaning. I do get in to the nooks and crannies as best I can using tightly wound swabs (i.e. that don't fray), but I've never felt compelled to go further than that. In fact, if memory serves the owners manual says that one shouldn't break the gun down any further than that, other than an armorer or gunsmith. If that is the case, then I would think Sig never intended owners to take it apart further to keep the firearm clean.

Thanks for the input, everyone. Just lubing the points that GG recommends during the trigger swap video had me thinking too much. I had seen the above video before and that is how I had done it before and will do it from now on.

I pulled the striker assembly out like the video above and had a job getting it back in. The little spring moved behind the safety lever (not sure I am using the proper nomenclature) somehow, and the assembly wouldn't slide in all the way and was binding (as you would assume) but I couldn't see why, right away. Finally the tiny spring fell out and then I figured it out, and with a little patience and common sense got it back in. Was a little nerve racking until I figured it out though.

Cleaning this gun is pretty easy and feels complete. Most other guns you don't feel like you could get it as clean. Too many hidden areas, but the P320 lets you access a lot more very easily.

I spray mine out with Hornady's Gun cleaner and lube.

I clean my P320 after each range trip, including the FCU but have never removed the trigger for cleaning. I have only 1,672 rounds fired but have had no issues.
