I Have two recommendations for this caliber and I will be buying both shortly if that helps in my stance on these weapons. I have been a 1911 guy for quite some time and wanted to expand a little for many reasons that I won't get into here.
The first, is the H&K P30s. Shoot one, do your research and you will know why.
Second is Sig P229 Enhanced Elite, again...shoot one, and research.
The unique thing with the Sig is that you can buy a drop-in .357 barrel and have an instant conversion to the Sig .357 round. Mag, frame, slide, everything else stays the same. (Sig .357 top round, .40 S&W on bottom)
