[HK SD9 Tactical]

Midwest Gun Works has the "select fire" or "heavy" firing pin for the FS2K in stock. It does not come with the spring. There are two different pins and the "heavy" pin is F484270040.

The regular "light" pin was installed to prevent slam fires on soft primer ammunition. The "heavy" pin is used with NATO standard ammunition but may result in slam fires if used with ammo that has non military grade primers in them.

FNH parts only carries the "light" firing pin for the FS2K now.

I've meant to pick one of these up for a long time. Thanks for the heads up.

Great item to have for the FS for those SHTF times.
