I have a new G26 and have used 115 gr. ammo at the range while practicing and getting used to the gun and have had no problems with the three different brands I've used. I want to practice, then stock up on self defense ammo and I'm wondering if there is any self defense ammo that is optimized for the short (3.46 in.) barrel in the G26. I've heard (scuttlebutt) that 147 gr. is not efficient in short barrels.
