They also said that if someone does bring them a Ruger to clean, that it usually takes about two weeks before they will get it back. Just curious, how long does it take the experienced Ruger owner (i.e., you) to clean and reassemble their gun?
I realize this is an old thread - I came across it in a search for something else, but saw the question so I figured I'd give my answer.....
With my old and well broken in MK II that I can take down and reassemble without any tools, I can take it down in under 10 (maybe 5) seconds and put it back together in about the same time - maybe a second or two longer.
I have a new MK III which is the first Ruger MK pistol I ever bought new - (I think I've had about a half dozen or so older Ruger MK I and MK II pistols over the past few decades) - - the new MK III is very tight and I need to use a heavy plastic mallet to get the pin (bolt stop that's also holds the MSH in place) out. So needing to use that tool (mallet) plus a punch (there's a gadget called a "Pistol Pal" that is a Delrin punch shaped to fit over the convex pin) it takes me about 20 seconds to take the gun down and a maybe few seconds more or less to put it back together. I suppose over time I'll be able to get the pin out and back in with my bare hands and it will be as quick as the older guns I've had and have. (or maybe not)?? - this is not only my first new MK pistol, but my first stainless one so maybe it's not as soft as the blued steel??? Or maybe Ruger is just purposely making the guns fit tighter - I haven't heard of anyone being able to field strip an MK III without using some force - and they've been around now for about 10 years so maybe it's going to stay tight forever

I've read that people have had problems with older Ruger MK I and II guns where the upper and lower fit got too loose and they needed to use shims to get them tight again, so maybe this is Ruger's answer to that problem (which I never experienced - even though some of my Rugers were 25-30 years old when I got them).
Another issue with the MK III is that back when this thread was more current the MK III pistols were newer to the public. They come from Ruger with a magazine disconnect which requires some extra time to field strip the gun and reassemble it. (a few extra steps are required - like removing and then re-inserting the magazine at different times during the process).... But since then, it seems that most people just get rid of the magazine disconnect with a replacement hammer bushing (they cost about $10 and are made by at least 5 or 6 different companies I can think of off hand) and that makes field stripping a lot faster (basically makes the gun function just like a MK I or MK II). Faster and more simple.
Peace,
