This last month replaced 938 and Kimber Micro 9 with a S&W 640 357 mag and a S&W 60-15 3" 357. The 640 is awesome at 15 yards with my 357 reloads. I carry 38 +P loads in it as my EDC. Still playing around with the 60-15 basically trying to get the accuracy out of it that I get with the 640. Heck with a longer barrel and adjustable rear sight it should b more accurate!
Dang I do love the 640, like a death ray in my hand!
