In the past there were some 1911's that did favor certain ammo over others and some that don't seem to care at all. It doesn't seem to have anything to do with cost or perceived quality either. I've been packing a 1911 for 45 years and I had one Colt that certainly had problems with Winchester ammo. Once I figured that out it worked fine until the day I sold it. I will say that no 1911 I've bought in the past decade has had any ammo problems. I'm not saying that steel Tula wouldn't do it but I don't shoot that. I really think that quality control all the way down to the low range of $5-600 has improved that there will be less and less chance of problems because of ammo failure to feed. One tip is not to keep all your mags loaded all the time. Rotate the one you carry or keep by the bed as a spring that is always compressed will be weaker then one that is newly compressed - that is true for all mags.
What most people call ammo problems in a 1911 is really an extractor problem where the last round case isn't fully ejected before the next round tries to load causing a stove pipe. That I have seen but it can be cured by literally bending the extractor by hand a millimeter. You can get fancy and file and polish but while I have done that I've never found it necessary. Just an excuse to use the Dremal tool. Extractor problems aren't limited to 1911's. I've seen it in Sigs, Glocks, Smith& Wesson and others over the years. Depending on how much you go to the range and shoot you'll see it too eventually. I'm the Chairman of my local pistol range so I am there a lot and probably see these things more often then most would.
Of course, shooting whatever you are thinking of buying is highly recommended but no other pistol has a trigger like a 1911 overall. It can be made as perfect for your needs as possible or works straight out of the box. You'll find that true of most single action pistols.
One last semi-hidden benefit of a RIA 10mm is that you can buy a 40 S&W barrel from RIA, drop it in, get a few 40 cal mags and shoot less expensive 40 cal ammo for most of you practice sessions. You do want to practice with 10mm ammo just so you can remember the difference, the 10 will kick more. There are a few companies that make barrels for the Springfield I just don't know if they go from 10mm to 40, Storm Lake is one and Fire Dragon is another. I'm sure there are some of the custom shops that could do it to at a higher cost.
