My complaint - as I've said, I got mine back in 1995 and that was during the Brady Bill & 10 rd clip crisis. When it's tyranny was over, I called HK asking if I could swap out old 10 rd spring for a larger 12 for which the gun was designed.
No - the company purposely designed the 10 rd clips to only hold 10 !!! Warning to all - when these people design something - they mean it.
I like h&k a lot but overall if I want a sa/da gun I like sig a lil better for the money. P220 is a fine handgun and fits better with the single stack magazine. Triggers are close but I lean toward sig. Sig also has a traditional mag release. If ya don't want 45 ya can always go p226. I don't really think glock is a fair comparison beside being polymer framed. Glock are economical but far from comparable to h&k or sig
