I'm a huge fan of the .357 SIG round, but have to say I've been a bit disappointed in the alleged feed reliability of the round. The bottleneck design of the round may be helpful in theory, but in reality the most common FTFs I've seen with any caliber round have occurred when the hollow point cavity hangs up at the bottom of the feed ramp. Personally I've had this happen more with 357 rounds than any other. Perhaps because the 357 round is slightly more prone to setback? Or perhaps something about the design of Speer's gold dots. Out of my glocks, I've never had a single FTF with 9mm, 40 or 45. I don't know why I'm cursed .357 issues across G33, G32 and even my Sig P239 with all sorts of different HP ammo.
