I'm wondering if I can purchase a new P99 9mm slide to go with my old model P99 frame. Are the 9mm and .40s&w slides interchangeable?

Why would you want to do such a thing?

My instinct tells me it's cheaper, after all is said and done, to buy another gun.

The 40 and 9mm slides are different (thicker on the front for the 40), but i've no idea about mounting or internal dimensions....i do know i would NOT try and mix/match frames and slides from one to the other.

As to old vs new 9mm slide/frame - dunno. I'll check at some point when i finish paying off my new (old) P99 tho.
