When you realize just much more difficult it is to machine a forging compared to simple bar stock prior to heat treating, you can easily imagine why Colt asks a premium price for their 1911s.
There are well known 1911 makers who claim "forged" fames and slides. The only "forging" those gun's parts have ever seen is the rolled steel as it comes out of the smelter.
