How can I tell if mine has them? Thanks!

I believe what you are referring to are the spring retainer half shells in VP lingo. They retain the spring on the firing pin. They are apparently called maritime cups by some of the aftermarket part companies who sell their version for Glock pistols. From what I can tell the 'maritime' version is made to help water drain from the firing pin assembly channel in the slide. I think that these cups / half shells in the HK VP9 are already made like the 'maritime' aftermarket versions for Glock pistols. The cups are half pieces that fit between the firing pin and the firing pin spring, and let the spring apply pressure to the pin. Rather than being a full round cylindrical piece when assembled that would sort of seal against the inside diameter of the channel / hole in the slide, the 'maritime' version has slots made into it to allow water to flow past it. The HK parts are made that way to start with.

Good info Thank you

Is that the info that you were looking for or are you talking about something else?

Good info, I didn't realize the vp9 had maritime cups. This will be useful to use a maritime tactical vp9 for backup, operating over the beach with a 416 with steel maritime mags. And a maritime finish Mark 23.

Maritime: it's the new black!

Operating maritime since KG

I thought about this a bit more and I don't think that this is really very much of an issue. This space is not sealed off on either side of these cups / half shells and should be able to drain, but I suppose it couldn't hurt much to make them that way. These parts are even more fragile than the firing pin spring assembly guide sleeve and that is why I have a few extras in reserve. Quite likely they will last a long time but they are cheap and small to store in case of failure / wear.
