I have been a big fan of the S9-A1, S40-A1 and M357-A1 Steyr pistols. Have one of each. They all are the softest shooting and accurate pistols I have owned. Totally trouble free for thousands of rounds. Always wished I had a 357 barrel for the S40-A1 as I enjoy shooting this caliber much more than the .40. Not available from Steyr. I checked. Was reading a thread on another forum and found a place that manufactures a 357 sig barrel for the S40-A1! Rim Country manufacturing. Seems to have very favorable reviews on the HK forums (they manufacture these as well). I will let you all know how it works. If any of you have used one, please comment here. Thanks.
