A 30 carbine pistol. Not sure what the gun was but it was LOUD!
;D My ol' man did that once with his .357 carry gun (Houston cop). We were shooting jacks just outside Pecos from my uncle's pickup. Brother wounded one, and the ol' man gave it the finishing shot. Half hour later, it was "WHAT was that you said?" "Huh? You talking to me?"City Slicker said:+1 .30 carbine Blackhawk
A buddy of mine shot one out the window of a pick-up truck we were sitting in...I couldn't hear anything for hours.
