Springfield 1911's in general have been somewhat difficult to come by lately, since 2011 anniversary of the 1911. I have seen them trickle in slowly lately though.
They do production runs and fill the pipeline & then switch over to other products for a while. Seems like last year they were real scarce about this time and then I saw supply catch up around February in the local shops around these parts. A call to Springfield should give you an idea of where they are at in terms of production plans.
Springfields definitely have their fans, but if you can't get it at a good price due to short term supply issues then their are a lot of excellent alternatives.
