Not if IRG is willing to bring it in, otherwise yes. For instance, there is currently no vendor in Canada with stock of either the FN or Federal offerings. Tradex (the usual source), is sold out. I am glad that I laid in 2000 rounds when I could, but that won't last long if I keep feeding both my Five-seveN and PS90.
What do you say IRG, are you going to offer the ammo again for these difficult-to-feed firearms?
