In my case, I bought my 9c as a replacement when the Chief said I could no longer carry my 3913. They are roughly the same size and since I got mine from an LE only retailer I was able to get 3, 12 round magazines so since I carry 2 mags off duty, I still have 37 rounds of +P+ Ranger T Series at my fingertips.
Accuracy? It is more accurate than my 3913 and far more accurate than my duty issue Glock 21. At 15 feet (with a rest) I can put 25 rounds into a one to one and a half inch hole ... off hand, during qualifications (timed fire), I group them into an 8 inch circle at ranges from 3 feet (hip shot) to 30 feet (double taps to the chest). My target's "chest" is so full of bullet holes that at 50 feet, I aim for and hit, the lower abdomen, just so the rounds can be seen and scored.
Trustworthy? Foolish, but the first rounds EVER fired from my 9c were during qualification, there wasn't enough time between purchase and requals to properly "break in" the gun. Now two years later, I have had exactly ONE mis-feed due to an oversized reload that only fed halfway into the chamber and had to be persuaded with a wood dowel down the barrel from the muzzle end (AFTER the gun was field stripped). Other than that, not a single hiccup or burp from the plastic fantastic.
I do plan on switching out the stock sights for some TFO sights, but that is just personal preference. With my eyes getting older, I'm starting to really need the high-viz sights. Otherwise there is nothing wrong with the factory trijicon sights (other than to me, they don't glow very well in the dark).
My opinion? Get the 9c, you won't be disappointed.
