My main concern here is the benefits vs the downfalls. If lube penetrates the cartridge (likely or unlikely as it may be), you have a dead cartridge. That is the downfall, and a huge one at that if this is a defensive pistol.

What exactly is the benefit here?

How many people here (or anywhere for that matter) have found corrosion in the bore of any pistol they've owned with a nitrocarburized barrel? If so, what environment was this pistol subjected to?

I always finish a barrel cleaning with light rem oil or slip 2000. Doesn’t seem to make any difference if I run a dry patch or not before shooting but then again the barrel isn’t really “wet”. Question: wouldn’t the first few shots clean out any oil in the barrel anyway?

If the gun didn’t blow up with that much lube dripping out, a small amount applied with a patch won’t hurt it.

I didn't talk about the gun blowing up. I talked about group sizes.

The question was about oiling the inside of the barrel, so I'm not sure the relevance of the Larry Vickers video??? I lightly oil my guns and I don't generally oil the inside of the barrel unless I know it is going to sit for an extended time. Larry has his opinion, but I wouldn't do that to any of my guns just to prove a point. They probably weren't his and he probably didn't have to clean them afterwards. To me it isn't about hindering the function with too much lubrication, it is about how dirty it is going to get after carrying for a week or having it in the field for a few days and/or running several hundred rounds through it with excess lube, what a mess! I think that gritty mess will lead to more wear/tear and failures to function. Equating under lubricating a gun and running a vehicle without oil is a "stupid" comparison. Try filling your engine oil until it is running out on the ground and see what happens!

I concur. There does need to be a proper balance between conditions and the necessary amount of lube for a particular weapon. The flaw in the Vickers test was that they went straight from lube bath to shooting, without any thought of exposing the weapons to dusty or sandy conditions.

The video was, indeed, largely irrelevant to the discussion about oil inside of a barrel, too. I can imagine that rapid accumulation of dust/sand in a bore that had been submerged in lube as they did would also have caused some severe problems for the bore.

The "test" was more of a stunt and left a lot to be desired.

I came into the habit of leaving a light coat of lube in the barrel of my pistols after reading to do so in the instruction manuals by the manufacturer. HK comes into mind right away for this. I don't see any harm with a light coat for protectant even if it most likely is not needed. I don't dry the bore before shooting one of my 9MM/.40/.45 pistol either as I believe the gasses escaping around the bullet would burn off a light coat anyway but even if not don't believe it is a concern.

Here is what HK recommends from the P30 manual, page 32

Light Lube - A finger run across the surface yields little or no lube.
Bore, chamber and exterior of barrel • All metal parts • All internal parts in slide and frame • Magazine spring • Recoil spring assembly • Metal magazine housing, where applicable

From Walther PDP and Sig P320 manuals, regarding lubrication... They are consistent, Light Film, One Drop of high, quality oil/CLP... and cautions about excess lubrication...
