I grew up a Catholic. We had several guns in the house. We were taught respect for life, and how to handle guns.
When I became a JW, with the anti-war sentiment during the Viet Nam conflict, I became a Consciencious Objector, and would not own a gun.
Several JWs liked to go hunting, and had some serious debates with the Congregation Servant. A letter was written to the Society about 1970-1971 on whether a JW could go hunting. The Society wrote back in support of hunting, and later published this in Questions from Readers if I am not mistaken.
When I in my exit process in 1992, I bought a Rifle. I lived in the country, and the Coyotes and Racoons kept going after my Chickins. I never caught them at the right time, though I fired at one, he got out of range.
Today, I have adopted once again my family training. I believe in self-defense, and in citizen militias as a last check and balance against government tyranny. This is the basis for private gun ownership in the USA.
There are about 280,000,000 guns in this country, about 1 for every person. While we have higher gun deaths than most western nations, we also have the highest per capita gun ownnership rates ... makeing our gun deaths to gun ownership ratio about the same as any other country.
Its all in the culture. Canada, for example, culturally has more trust in their government, and it works for them. I admire Canadians. But Americans could never do that. We trust ourselves individually first. We fear too much organization.
PS: To more directly answer your question: JW gun ownership until the early 1980s was likely lower than the general population because of the stand they took against war. Also, being a police officer was frowmed upon. In the early 1980s the Society prohibited JWs from owning handguns. So, the only remaining JWs owning guns would be those who had hunting rifles.
Following Bible principles, we will avoid trying to live - or demand others to live - by an extensive and rigid set of dos and don'ts that go beyond the teachings of the Bible. The Watchtower, 4-15-02, pg 22, pp 15
