For those looking for normal capacity mags, HK has new, all polymer, translucent mags in their webshop (https://us.hkwebshop.com/HKWebShop/s...mID/10116//279). And price... it does not look like "HK price" a bit to me.
I handled this mags here (still waiting to get some for test and review) and they really felt solid. And HK usually do not turn out stuff that does not work.
