Does anyone know of a source for the 19mm signal cartridges for the HK flare gun
that has the removable 5 round magazine?  
It seems the larger flares are everywhere but I'm having a difficult time finding any of the 19mm ones. One source told me they were never imported in any great number. I bought this HK
flare gun when I bought my HK 91 in the early eighties and I'm first running low on flare
cartridges.
Thanks in advance.

Thanks for the info.  I'm looking for the red flares but is it a source.
(Wow, you don't want to pop off these babies too often at that price!)
