I've got several boxes of Federal's 115 gr +P+ ammo that I've tried out in my 6906 and it's very accurate. I'm a bit concerned as to whether this particular ammo should be shot at all in alloy frame pistols however...especially this one. I don't intend on using it on a regular basis but since it does so well with accuracy/feeding, I'd like to use it perhaps down the road as a carry round. I'm I treading on glass doing so with this high pressure round in an alloy gun?
