Generally, yes. But, there may be complications with Kydex as, many times, they are precisely molded to specific models. The cheap stuff (Uncle Mikes and Fobus) will be the same. More expensive offerings, you may have to ask the manufacturer. I haven't encountered a leather holster that won't fit CW, K, MK, P, and PM series guns interchangeably (albeit a little lon for the PM guns). The CW series guns are likely to be just a bit blockier about the slide than the K series. That's the only complication I can see.
