Nebraska Hunter: I think you know exactly what you want and if you are looking at the Springfield line then look more closely - a number of their models have very good carry sights with nice big square front blades and nice open square rear notch sights. Just look at the different Springfield models and you should find the one you want. Get onto their website and review their offerings.
You can also get a nice selection of trigger styles and grip safety styles that can confuse the eye even further.
I would suggest, as the moderator of this site, that you peruse the last few pages of this site to see what others have said in response to similar questions.
We have a couple of posters here whop have an incredible experience with the 1911, including putting together some fine pistols, and these folk have provided a long list of great information for those who ask. In fact, I think that just a few posts down are a couple of good threads that should help provide some solid suggestions.
Also, further up the line in the General Handgun forum is a post about the RIA 1911s and it is worth reading. When you have finished with that thread check back here for what SharonAnne and willianlayton, and others, have written and then you should have enough information to make your decision. Hope this helps. Mikey.
