A 5" 1911 barrel is 5" from breach face to muzzle.
A 4" model 25 is over 5 3/4" from breach (recoil shield) face to muzzle.
My 1911 will only reliably function with certain bullet shapes and power loading. My revolvers function fine with a 185 grain bullet at 650fps or a 255gr SWC at 1000fps.
I have acp revolvers from 2 1/2" to 6 1/2" in approx 1" increments. I should crony them all.
