I had a Springfield MC Operator and sold it. The guy I sold it to still has it and loves it. To me the MC Operator was ok but, just ok. I have a Springfield WW2 GI, and it's ok. I still like shooting it but like the MC it's just ok. I think the Springfields have a cheap cast feel to them. Having said that both of them, the MC and GI, worked fine. I have a Colt RG and an XSE Commander and both pistols are excellent in almost every way. The XSE needed a little spring tuning to get the trigger just right but, over all is an excellent pistol. The only complaint I have regarding the RG is the finish on the slide has holster wear on its leading edge. Its has been drawn quite a lot over the past four years but, I think the finish on the MC is more resilient. Both Colts I have are very well made and have a solid feel to them. So I would go with a Colt RG over the Springfield based on my experiences, unless you can get a great deal on the Springfield.
