Here Is a Summary Of the .45ACP vs. 9mm Debate This Week
Last updated: June 7, 2026 · Originally published: January 18, 2018
Have you been following the caliber war with Rob Leatham and Rob Pincus?
It started on Monday when Leatham ignited the fire again arguing for his preference of the .45ACP, and provided a compelling shooting demonstration.
Toward the end of the video, he called out Pincus for more debate on the subject, who took notice right away.
Pincus then responded yesterday on his I.C.E. website and with further explanation via Facebook Live.
Now it looks like Leatham has asked Pincus to meet at the Worlds Collide Facebook page tonight at 6:00 PM MST to talk through it. We cannot wait!
I own and carry 9mm, 40S&W, .380, and 45 ACP. I carry according to daily location but I always have my .380 in my back pocket. I prefer 45 ACP. and carry it most of the time. However, there are locations in metro Kansas City where I opt for my 9mm (20+1) over my 45 (12+1) all because of the bullet count.
9mm concealed.
.45 open.
The question is….’will Pincus be packing a .308 cal. pistol IWB?’ While he’s sitting no less. Leatham will have to up his game if he wants to compete at that level—perhaps “up’ is incorrect, and ‘shrink’ his gut….I mean game is more appropriate.
