Everytime this topic comes up, we see the same advice: Grow some, be a man, be an adult, grow-up, etc
Sorry, that is garbage advice. Why?
1) It's advice coming from people who long ago made a decision that this sport is a high priority in their life.
2) It is generally (though not always, thanks for mentioning) coming from people who are not in that situation
3) It forces the "It's me or the guns" decision when that decision might not have to be made.
4) The people asking for this advice have generally not made the decision that this sport is a high priority in their life.
Here's some more thoughtful advice:
Step 1 - Try to identify the reason for "I don't want guns in my house" It may be possible to find a solution to her problem without forcing a "I know you don't want this, but tough" confrontation with someone you love.
Step 2 - Once the issue has been raised, try to provide a mutually acceptable solution. Solicite a mutually acceptable solution from your wife/girlfriend. - I really enjoy this shooting, it makes me happy/relaxed/destressed, etc. In order to continue to improve, I need my own firearm. Is there something I can do so you'll be comfortable with me having a gun?
Step 3 - Repeat Usually, once you address 1 concern, a new on will come up. This means you'll have to go back through it. It can be tough, but try to give it some time.
Step 4 - While going through this, try offering to let her try shooting. Offer to take her, offer to pay for her to go to a "Lady's Night" (as long as it isn't the night you ALWAYS go shooting) offer to pay for her to take a class, try to find something she's comfortable with trying. Offer and encourage, but don't push.
Step 5 - If you've done all of the above and you feel like you aren't getting aware, now you have a priority choice to make:
1) Conceed to her needs/desires/fears. Decide she is more important to you than the sport and that you're not going to push it.
2) Conceed to her needs/desires/fears. Decide her happiness is more important than your convience and look into an off-site storage solution. If you're the member of a range, they may be willing to rent you space in their safe. If you always go shooting with the same friends, ask if they have space (or are willing to store a safe for you) and are willing to store your guns at their place for you. - This eliminates the ability to use that gun for self-defense
3) Decide that the sport is worth the risk. Pick up a safe, cable lock and trigger lock plus a gun. Partially disassemble the gun, install both the trigger lock and cable lock on the partially disassembled gun and store it in the safe. Don't buy ammunition. This should minimize the impact, but understand that you are still risking the "You chose guns over me" reaction.
4) Decide that the sport is worth the risk. Pick up a gun, ammunition and safe. Toss the gun in the safe, store the ammunition seperately. Less hassle, but also less accomidating of your wife/girlfriend's wants/needs/fears.
5) Decide that the sport is more important than your wife/girlfriend's wants/needs/fears. Go out and buy a gun, store it according to local safe storage laws. Be prepared that you've forced the issue and created an ultimatum and be prepared to accept the results.
On the flip-side:
If you have been involved in shooting sports and have several guns, you need to make sure when you start a new relationship that the person you are getting involved with knows and understands your hobbies/sports/lifestyle and accepts it before the relationship gets serious so you can deal with this issues long before they become problems.
