Hello I'm not having any luck on finding the X-Grip for my 320 subcompact, I'm looking for the grip adapter that allows my 320 compact 15 rounders to be able to be used in my subcompact. I've checked about a dozen sites, and either their out, or the wording is confusing, like it's for the 250 subcompact with new grips. If anyone could provide me this info I'd be a happy man, thanks.
