I have obtained some white box Winchester 9mm +p+ 127 gr. SXT (Q4280). Is this the same load as the Ranger 127 gr.?
Thanks.

Yes,
Under the "older" part numbering system this is the Ranger loading with "talons".

Under the new system identifyable by the tan box you need to look for the R designation.

I have a Kahr K9, think that stuff would hurt it? Sam

By "hurt" it I assume you mean cause premature wear and that we are discussing a new or like new pistol in perfect working order?

Yes, by all means shooting above pressure +P or +P+ ammo in your firearm will accelerate the wear on your firearm.

Now that said, the K9 is a very strong firearm made from high grade steel.
The difference in wear in an alloy frame is often 30% reduced service life if the user was firing +P or +P+ ammo for the entire life of the pistol.

The original Kahr numbers provided when the pistol was first produced placed a service life of between 25,000 to 30,000 rounds with 9mm NATO spec ammo.

Will you be shooting 7-8,000 rounds or more of +P+ ammo?

If the answer is no, then by all means use the +P+ ammo as much or as little as you would like. Your pistol will not "detonate" and you will have a round that performs as well or better than most of the .40S&W loads out there with less recoil and one round of increased capacity.
