Check the offerings at Rock Island Armory, they make two , a model CS with a 3.5 inch barrel and a model MS with a 4.25 inch barrel , both seem to be steel framed ( but double check that) . The MSRP on both is $546.00.

STI Ranger II. Though I don't see them offered on STI's site. They're still out there. Will be buried with mine! Looks like they redid their website recently.
I have a Kimber Stainless II and love it. Just 500 rounds through it but functions without a hitch. The Stainless II has a 5" barrel but lots of 4" - 4.5" Kimber variations out there.
Dan Wesson CCO. 4" barrel with full size grip. Steel slide & alloy frame. I got mine about a month ago and am still breaking it in. Instructions say to shoot 50 rounds and then clean the gun. I don't like to take my gun apart at the range, so I shoot it and then bring it home to the shop to clean. It does get me out the range more often, so far.
It is a sweet shooting gun. I got mine new on GunBroker for $950 which was a pretty good deal.
