I've had my 9C for a little over a year now, I rotate it as my EDC with my shield 9.
I shoot the 9C much more accurately than I do the shield (pretty big hands), but if
the shield fits your hand, with the MagGuts+2 kits (which I have several of) you can carry
a shield as a 10+1 with barely a 1/4" of extended length on the 8 round mags.
I don't really notice the extra weight or width of the 9C IWB or OWB
(stealth gear Mini and Flex with a Bigfoot belt).
I'd go to a range that rents both and shoot them back to back and see what tickles
your fancy more.
The deals on the shields right now are crazy good (if that gun will work for you).
on the forums I frequent I am actually seeing these go regularly for between $350-400.
these aren't shields, the used shields go for real cheap, the 9C's .....not so much,
you may be able to find a sweet deal out there (I did last year $350 , brand new fully
stippled trigger guard undercut and 5 mags(one full size with the sleeve) , but that is the best deal I've seen
on one so far.
I see the 40C go for closer to $300 more often than I do the 9C.
I love mine, if it was just a tad lighter , I don't think I'd even carry my shield at all.
