That model looks almost identical to mine except it has adjustable sites instead of my 3dot. I have the PX9151LP. Read a thread I started which talks about it and a Colt I picked up.
When push comes to shove it is a good gun. I love the finish on the gun but the Cocabolo grips look orange to me rather than dark reddish in the picture.
I prefer the GI guide rod over full length ones for ease of maintenance and swapped out mine with a new spring and springcap. I also prefer the 3-dot sites but thats just me. :-)
I see some on GunBroker.com and the cheapest around $870. http://www.gunbroker.com/Auction/Vie...Item=196656673
I consider my Colt to be better quality but more expensive. If I could just merge my Colt and Springfield into one gun it would be the perfect 1911 for me.
Springfield has a good name and I am sure you will be happy with it.
