Every month or two I get an email from a CS45 lover who needs parts. I don't have any CS45 specific mags but I do have an 8-round gold-plated and two 7-round mags which fit, stick out a bit and so they act as an extension. But they shouldn't be slammed into place. I also have two used barrels in excellent condition and one mint barrel unused. If interested email: [email protected] BTW I would take advantage of Skip Ritchie's custom holsters since CS45 holsters are difficult to locate.
