I've got a Steyr M357 -- and a Kel Tec P-40/P-357 (yes, a Kel Tec in .357 Sig.
) KT used to stock the .357 top end for the P-40 for $175, the drop-in barrel alone was $110. It is an inexpensive way to get into that cartridge. Of course, when the Steyr wasn't well known or popular, your could pick up an M357 for $299.
I find the recoil no worse in the .357 than the .40 -- maybe even a little less with the lighter weight projectile. Yes, it is accurate as well. The low bore axis of the Steyr and short reset trigger makes it a real performer in this cartridge.
Here's a link to an informative website regarding this cartridge -- and a list of agencies who are utilizing the cartridge. http://www.handguninfo.com/Archive/www.Pete-357.com/#Agencies
