Just out of curiosity here, how many who have "thousands" of rounds through things without cleaning them, ever ran into breakages and other issues that were or would have been missed because you weren't cleaning and "maintaining" the guns on a regular basis?
I haven't had too many problems over the years, but I have had a number of guns that had parts break due to use, and while the guns were still, for the most part, running with the parts broken, knowing when they might have stopped because of it is anyone's guess. Usually, at least for me, it seems anyway, that sort of thing would happen at the worst possible moment.
Cleaning is only part of this, the other part is just a general inspection of what you're cleaning during and after looking for any possible problems and fresh lube to help with the wear and tear. Just letting things go, for whatever reason, just doesn't seem like a smart thing to me.
I know that most guns (22's have always been the exception here for me) that have been kept cleaned and maintained, will generally go a long time without function issues. I don't need to prove that to myself. Ive had a number of guns go multiple cases at an outing without issue. Ive also had some not get through one before there was trouble.
I also know that any of those guns are starting "fresh" at each outing, are more likely to work longer and without issue, than something that's not been maintained, and who knows where they are in the "fixing to choke" cycle.
And of course, all of this really doesn't matter much if what you're using is just a range toy and not going to be used where it may be counted on for something serious. If this is the gun you carry and or are using for that, and plan on counting on, then I would seriously rethink things. Just "wiping it down" isn't maintaining it.
