I was planning on building a suppressed SBR in the very near future for home defense exclusively...but I was at a gun shop today and heard this:

"Shooting a suppressed 300BLK has the energy equivalent of shooting a suppressed .45, except with less mobility."

Sure, I can get on target faster, have a bigger magazine and can place shots on target a little quicker at home defense distances...but he has a point, and there's over a $1000 difference between a good canned .45 pistol and a good canned 330BLK rifle. Can someone reassure me?
