If you take two pistols of same make and model why does one shoot anything you feed it and the other will only digest certain rounds? Curious about the specific variables that create these idiosyncracies. I had a .380 Sig 230 that would eat anything except 95 grain Hydra-Shok. Recently I was trying out a couple of different .40 loads in my Beretta 96 and had a couple of FTF with Gold Dot 155 grain. I have never had a problem with any other round and have settled on the 165 grain Remington Golden Saber but it does bother me that the Gold Dots had issues.
What makes a pistol ammo finicky?

While I can't really comment on this exact scenario since I only have one matched pair, I will say that the number 1 reason some pistols are finicky is tolerances. The tighter the gun, the narrower the selection of reliable ammo seems to be. Certainly theree are other factors, quality being one of them. Also the caliber: While .40 S&W loads tend to be very close across the board, 10mm has a very wide spread, power-wise. .45 ACP has the same issue, to a lesser extent. A gun that runs well with light loads may not like the warmest stuff, or the reverse. And some guns just don't like certain bullet designs. I've had a number of auto's that didn't feed truncated-cone shaped bullets well at all.
