Personally, I would vote against getting the 3-1/2" bbl 1911 for your first 1911, IMO. These guns are known to be finicky & not easy to shoot accurately (regardless of maker).
For your first 1911 I would strongly urge you to go with a Springfield Armory 1911 5" Govt model for multiple reasons.
1) Quality for the $. Unless you get into the $1,000+ range of 1911s, SA is hands down the brand to go with.
2) Customer Service. Should you ever need warranty work, SA is known as among THE best in the bidness. End of story.
3) Resale value. SA holds their values well. Colt may have the edge in this catagory, but SA has the edge in quality control.
4) Availibility. SA's can usually be easily had, with a few exceptions.
There's also nothing wrong with buying gently used. Quite often one can score a higher tiered 1911 gently used for what one would get a new lower tiered one. Just be sure to buy one that's NOT been worked on, no matter who the seller claims did the work. After all, YOU have no way of knowing if he's telling the truth on this or not. Get one in 100% factory OEM condition or pass on it, IMO.
Good luck!
