A 9mm in either of those two brands will do just fine, if you have the training to go with it.
The gun and your equipment are important, but not nearly as important as the training.
Over the years I have had to carry many different types of firearms, and without a doubt the most important asset I had in my arsenal was the training I had received.
If you are serous about concealed carry, the training team at Davenport Guns would be happy to get you started down the path of skill at arms.
Of course Davenport Guns offers the standard state mandated training, but they also offer combative firearms training opportunities on a regular basis, hosted by Pulse O2DA certified Combative Firearms Instructors (CFIs).
If you are interested, please check out this link which gives you an overview of some of the training now available here in the QC.
