I guess the WT's own Awake magazine must be lying then: Quote edited to make the point.

When You Are Threatened
That was a good article. At the time, i thought it left things open to the conscience of the individual. But, then they wrote the July 2017 QFR which in part says
How a Christian chooses to protect himself, his family, or his possessions is, of course, largely a personal matter, as is his choice of employment. That said, Bible principles reflect God’s wisdom and his love for us. Out of regard for those principles, spiritually mature Christians choose not to keep a firearm for protection against other humans. They know that true and lasting security comes to those who demonstrate trust in God by living in harmony with Bible principles.—Ps. 97:10; Prov. 1:33; 2:6, 7.
As for me and my household, we choose our guns.
