All I know is that the factory Speer 124 Gold Dot has a 1.12" +/- OAL that works.

I had a test at 1.13" in my 5" and a 1.08" OAL in my C9 3.5" and had malfunctions, with the factory bullet in my two 9 mm pistols.

These test might work in your pistols but it does show that OAL of a load is important.
