Combo of what? You've listed a synthetic motor oil and CLP which stands for clean, lubricate and protect. I can think of at least 20 products that are called CLP or have that in the name. To which do you refer?

I'll say it like I do on all these threads. People overthink cleaning and my suggestion is ONE and DONE.
Ballistol, Slip2000 or any single lubricant that cleans and lubricates will work just fine. I see people with 3 or 4 bottles sitting on the table. This is for the barrel, this is for the slide, this is for blah blah blah.

Go get some Mobil 1 oil if you want. It will work just as good as anything else.

Good luck.

Hopped no.9 synthetic won't harm plastic or nickel. But I see it's now discontinued.

I grew up using Hoppes #9, but no more. In terms of safety, I would be much more worried about what it might be doing to your health rather than any harm to a gun. A gun is just a tool and easily replaced. Your health not so much so. The hierarchy is the gun is there to protect me, not the other way around. There are way too many good non-toxic options available to use such an outdated product IMO.

Any good solvent will work fine. I use rem oil and a little grease on the rails and I am good to go

Your grandpa. Hoppes #9 retains it's popularity today because it reminds you of the first time grandpa let you shoot his gun even though you can't remember it.

I also love the smell of a tire store.

I also have used Frog Lube on my M&P's, on my 2011's I use Brake Clean and Mobil 1 (because I clean them more often and it's quicker and easier. Spray the brake clean to get the powder residue off, then blow it dry with compressed air and drench it with Mobil One 0W-20 (same stuff that both our cars call for, I take the dregs of the bottle for gun lube). I clean the STI every match, the M&P....when I feel like it.

I've used Butch's Bore Shine for years. In my rifles I run a patch down and let it sit while I watch the golf match. Go out about every 30 minutes, run a brush down, then a clean patch and more Shine. After about 9 holes it's pretty clean. Hey, you gotta measure it somehow.

In my pistols i only shoot lead. Use Bore Shine on those too but after letting it sit for a bit get a mob and wrap it with ChoreBoy. Clean in about 5 passes. Been trying Kroil lately to see if it loosens the lead better but so far haven't really decided it's any better simply because the ChoreBoy is what really cleans out the lead.

I agree, you can overthink this.

Give a look at Hoppe's Elite Gun Cleaner , smells good, low odor and safe on plastic. I can clean a gun with it and put it on the night stand without my wife complaing of the "smell" , she has the nose of a bloodhound. And it's a decent cleaner .

How resilient is a pistol barrels rifling? I shoot air rifles and I know the rifling is easily scratched so we rarely clean the lead out of them. Also helps with accuracy

Well, I have 8,531 rounds through one pistol and the rifling is still very good. As long as you stick to a brass or nylon bore brush you'll be fine.
