Has anyone seen an STI or other high end brand that makes a quality +2 or 3 for a HK .40 (USP style) magazine? I know they are everyone for STI guns and Glocks, but I can't seem to find one for HK, maybe one works for more than just STI's?
I've actually got a funnel jet on my Tactical and Expert both in .40SW so I need to know the same thing... anyone else tried it out? I'm actually using the 16 round mags.
Hey all, Robin Taylor here. I was recently approached to build a +3ish extension for the HK USP Expert (and it would also work on the standard HK USP). Curious how much demand is out there?
