Prices for new ones vary, but run from $950 to the retail of over $1100, now. I don't think they are worth that much, frankly.
I have the SR1911 Target and it won't shoot nearly as well as my new Springfield Armory Garrison. Same ammo, same magazines, same reliabilty, but the SA shoots better. While I like the Ruger, it's not as nice as that Garrison.
