I found pocket carry to be a mess.
Yes it's easier and if that's what you need to do to carry, then go for it.
I just found way too many disadvantages for it.
As far as 9mm in the front pocket. If you're willing to "dress" for it, I suppose so, but it would have to be baggy to some extent or you'll have a noticeable odd rectangle in your front pocket. This bothers some people, others assume, it will be thought to be a big cell phone or something.
Lots of variables depending on you.
Can on speak on my experience and I found pocket carry to have more drawbacks than benefits.
