1. A few years, I think, because...
2. Since I was 13, I think. First single-shot 12 guage for Christmas.
3. Bought a couple more in my 20s and sold them for financial reasons.
Now back up to "several"
Finances are less of an issue for me now, I make more per hour, and am blessed with more over-time than I know what to do with. Plus, being divorced, there's no spouse to scold me.
On average it's been less than one per year. Last year was different.
A wonderful sport to enjoy, yes. Watch out for Glocks, and anything refered to as a "snubby" or "j-frame". Glocks are 3x as addictive as crack. I'm still kicking myself 10 years later for selling my G19.
And you'll read about J-frames following people home like a lost puppy over and over and over.
