Recently, my CCW rotation includes these two. A Springfield XDS .45, and a S&W 442 in .38 Special.
They are almost exactly the same size, and both fit easily, with holster, into my front pocket. The Smith is a bit lighter. 18 ounces verses the XDS at 25 ounces. That is with both loaded, 5 rounds. With 6 rounds, the XDS comes in at 26 ounces.
