This 4.6" 45/45ACP Flattop, Will not eject the 45 Colt completely.
I run ACP cylinder most of the time just because it will eject them shorties completely.
Don't let the Birdshead Grip fool you, that has nothing to do with the Standard 4" ejector rod that all 4.6" guns have.
The Number 5 Base pin is a tad shorter, still no workie…
Currently has a COLT head Basepin, a very short button, but I have not tried 45 Colt Brass ,,, yet.
