Every time I go to the range, I shoot the R9 and one of my other three carry pieces (Seecamp .32, Boberg, Kimber CDPII), even if I'm going to the range to sight in a rifle or to punch paper with bigger pistols. All are kept clean and lubricated (Eezox works best for my small pistols) and all work flawlessly if I do my job. I rarely put more than 50 rounds through the R9, and often only 20 to 30, just to keep "point and shoot" proficiency, not to demo how accurate I can be with aimed slow fire, which I also practice...in that sense the R9 is not a "range gun" but that does not limit my use of it. The Kimber is a tweener, since it is accurate at considerably longer distances than the R9 and the LWS, and with it I practice both point and shoot and slower aimed fire for accuracy. I'm still working on the Boberg and don't carry it yet, but may end up doing so in the future.
Moral: shoot the R9 all you want...mine works well with most ammo, but I stick to Lawman for general practice and Gold Dots for practice and carry and I change springs every 150 rounds. As with any closely toleranced machine, prolonged and extended use will eventually cause wear, so if one just wants to throw a lot of lead downrange I'd recommend getting a Glock.
Advice:
1. Treat it right (good ammo, fresh springs, clean and lube, don't overheat it when shooting)
2. Hold it tight
3. Ignore the bite (or wear a thin leather glove for extended practice)
4. Forget the sight (point and shoot in CQB)
5. Carry light (smallest and lightest high quality 9mm, absolutely dependable once you break it in and
learn its ways).
Corollary: Sometimes fresh from the box and even after recommended take down/clean and lube before shooting there will be malfunctions due the to close tolerances. Put 200 rounds through it (not all at once...let it cool for best function) and if problems still occur with good ammo and fresh springs, Karl will fix it.
