Call Bob at Plainfield Shooting Supplies. He usually stocks a fair amount of H&K.
Since the match has been out of production for many years forget looking for one at a dealer.
Here is one. This is about the going rate.
WTS: HK USP Match .45 acp NIB $2500.00
Any place have HK USP 9mm mags?
I'm kind of surprised how fast they disappeared since I didn't think the platform was that popular. I have yet to find any anywhere.
I may just wait a while. I have a couple WTB ads out and people are wanting more for used usp 45 compacts than I can buy a brand new usp 45 tactical off of gun broker for. These are funny times.
