There is no way you can compare "factory reloads" to first line, major ammo company self defense ammo, or even to boutique brands like DoubleTap.
My experience with +P+ Ranger ammo is in four different brand pistols, and in two Glocks. No problems with any of them.
In fact, I started using this ammo after reading recommendations from Massad Ayoob and browning HiPower expert Stephen Camp.
Still waiting for my Flashback...I would like it now, please.
