Anyone know the best source for UMP 45 mags, HK and the quality US made ones.  Any deals?

I have no trouble with the US made ones from HKparts for $50.  25 or short 15 rounders work.

I did buy some 2nd hand early Gen USA ones a while back - that don't work reliably - the later ones from HK parts currently seem to work.

Has them in stock if you want the real deal. They need to be had when the hadding is available. They were a tough item to get when I had my USC to UMP conversion done.

Anyone heard of any new 45 ump mag deals for the upcoming holiday?

Having been stalking this for years, I’ve yet to see UMP 45 mags of either German or American origin be included in a sale.

I ended up spreading out purchases of the US-made ones from HKP over a few months so I didn’t spend a fortune all at once.  There just isn’t a deep pool of surplus to draw from unfortunately.

HK USA had used German UMP 40 mags for $43 a pop last year that I stocked up on when I did the .40 conversion on my Gideon Shadow build.  That’s the best deal I’d ever seen on UMP mags.  Sold out now, of course.
