get a damn gun, preferably a high quality accurate rifle

[Grumpy]

and get the mandatory matched supporting accessories
ammo, at least 600-1000 rounds minimum and several matching magazine's and a rifle cleaning kit, learn exactly how to sight it in and use it!
you may never use it but if you need it you'll need it very badly
