While some would argue, the differences between the two are small. If you plan on practicing a lot, and $ is an issue, know that the .40 will run you more $ every time you use it.
I chose the 9c over the .40 because it was sufficient and more economical. Recoil and control is very nice on the 9C, but don't know about the .40 .
Post your final decision here, when you get it!
