I just purchased a couple hundred rounds of the 9mm +P Short Barrel Gold Dots for my G26 and ran 100 through my G26 and 20 throug hmy G34 to check for function. The remaining 80 are to keep for defensive use: 21 for daily carry and the rest to refresh my carry gun every 6 months or so. Call me anal but I unload my carry ammo before I get to the range, mark the case that was chambered with a sharpie, and head out to the range with cheap FMJ's. When I get home, I load up again placing rounds that have been chambered at the bottom of the magazine so I don't chamber and eject the same rounds over and over. When I've chambered each round once or twice, I burn it up on my next range trip and replace it with fresh ammo.
They really seem hot compared to the 115 grain gold dots I've been running. Recoil was about what I would expect out of G27 or what I would expect a .357 Sig to feel like and very snappy. Not abusive or anything (it's still a 9mm) but was a lot more than I expected or was used to after running so much White Box 9mm. Don't regret going to them but would try a box before I stocked up on them.
As with any round you intend to use for defensive use in an autoloader, I'd run several rounds of it through any pistol you intend to rely on for defense to check for 100% reliable funcitoning. Shouldn't be a problem, especially in a Glock or Sig, but you want to KNOW your gun will feed them when you need it.
