I have tried the 135 grain Gold Dot, and while its an OK load, it was not consistent in either of the snubbies I tried it in (a S&W Airweight .38 Special and a SP101 2 1/4" .357), or in my 4" 681. The standard deviation in all three guns was around 50, as opposed to about 20 for the 158 grain LSWCHP (+P) I tried.
The 158 grain load offers a heavier bullet (which I prefer for .38 Special), shoots right at POA in my fixed sight guns, averaged only about 40 fps slower in the snubbies, had a higher muzzle energy in the snubbies, higher momentum across the board, and higher sectional density. The Gold Dot might be more likely to expand, but really that is the least of my concerns.
I'm going to stick with the 158 grain SWCHP(+P) for my Airweights and I expect I will be using the Buffalo Bore (+P) offering in my newly acquired Ruger SPNY when I make it to the range to qualify.
I would carry my own handloads using a 170 or 200 grain SWC or SWCHP if I could, but my department allows factory ammunition only.
