Sell the Ruger and buy a Glock 21 or Glock 30. Easy to shoot, reliable, anyone can maintain them and parts are all over the place. Even folks that are admittedly biased against them, run out and buy one as soon as world events make the landscape seem unstable. Best of all, there is a ton of information out there on the web and in books for you to learn virtually everything about maintaining and shooting your Glock.
The Ruger is a dead platform. You asked for maintainability, and the Ruger doesn't have it. It is out of production and Ruger is even selling off their remaining parts last I checked. They are not fully user serviceable either IIRC. It's supposedly very reliable, but I'm not sure that means much coming from it's target demographic, which doesn't really include harsh conditions or high round counts. A reputation of reliability doesn't mean anything if a oddball spring or pin busts leaving you high and dry.
The 1911 is a nice gun, but it's 2015 and the only folks that are still asserting that it is as reliable as more modern guns are severely emotionally attached to the platform. And while their knowledge and experience is valuable and appreciated, it's time to stop pretending that it's not potentially a very finicky gun. It's definitely maintainable as there are more parts out there than you can count, but most take an experienced touch and tools to fit correctly. Lovely gun, everyone should have at least one, but nobody should have to depend on one. If you do have to depend on one, make it a late production Colt or S&W E Series. EDIT: (My own 1911's have actually been flawless, but I'm pretty paranoid about keeping them lubed and clean, and I never attempt to fit or install any aftermarket or replacement part on them myself. I know that I'm an outlier because I certainly don't see other 1911 users sharing my experience, even if they do insist otherwise.)
If you simply are against Glock, your other next best options (without investing a wad of cash) would be a used Sig P220 or S&W 4516 or 4566. Very reliable, serviceable, and shootable. But still are dependent on the factory for some repairs. The Sig factory will refresh any gun you send them for a small fee ($85, cheaper if on sale iirc) by replacing every spring, and replacing any small parts that need it. For a few bucks more you can get refreshed night sights, action jobs, barrel re-crowned, etc, etc. On the other hand, S&W is trying to distance themselves from their steel 45's, but are still working on them.
