Welcome aboard...there's a few of us OCing around the Springs (rarely myself though).
1. It is illegal to carry into schools (or property if you don't have a CHP), federal buildings and of course, you can't carry past metal detectors. If you venture out of the Springs, the above is still true no matter where you go in Colorado until you hit Denver city limits, where OC is totally prohibited, so don't carry there unless you have a concealed permit.
2. Colorado Springs city-owned buildings have a blue signs on entry doors at eye level stating that OPEN carry isn't allowed. By law, they can't prohibit legal concealed carry. These include places such as Pioneers Museum, the airport and Memorial Hospital. Private businesses are allowed to post whatever sign they like, there isn't any sort of standard.
3. Legally, you can carry your pistol in whatever condition you like.
4. We do occasional meet-and-greets at various locations now and then there's a member in Aurora who seems to like meeting up with new OCers to help them get over their nervousness, I'm sure he'll be around shortly to introduce himself.
