As a general rule, if you aren't subjecting your sidearm to extreme abuse and filth, you don't need the extra that a Sig or H&K provides. If you are testing them to that extent, you probably aren't paying out of your own pocket.
Want is a whole different conversation, of course.
My SR9c runs dry, and it runs without frequent cleaning. It runs wet. There is nothing that I will subject it to that it can't run through. The tolerances and fit are very tight, but it cycles smoothly. For a concealed carry weapon, there is literally no other weapon that I would rather carry.
...and for the price of an H&K 45, I got my SR9c and a Walther PPQ.
