I bought a P938 recently with this laser installed. I am not much of a laser sight guy, so I took it off. It works great. It will fit on the P238 as well. I have included a screenshot of an ad for it on Amazon so you can do more research if you like. I do not have the tool to install it. I had the guys at PFI LLC take it off, and I'm sure they'd install it on your gun.

PS. I had this listed before, but deployed recently. I forgot I left it listed. If you contacted me about it but I didn't respond, I am sorry. I did not have my usual methods of communication.
