I have always said one of the secrets ( or not so secret ) is the HK mags are best mags made on planet earth and are a huge part of their unreasonable reliability. I think they advertised the P30 with a 90,000 round torture test. They cost a lot, but they are amazing IMO. Ive never cycled a slide to put a round in the chamber that feed the round so effortlessly, like silky smooth.
P30 is some goodness, can't wait to get a dot on mine for my blind ass.
