Here is an interesting post by a member from another website. He tested the 124 gr+P Gold Dots against the ones loaded by Underwood. Those are the same 124 gr Gold Dots loaded at +P+ velocities.
What I found interesting is that if one loads these from a short 3 inch barrel, you get the same velocity as you would with a regular Gold Dots from a 4.5 to 5 inch barrel.
