Since this thread has dug up all kinds of memories of using & enjoying the 870's,, I'll share one of my favorites.
I've kept an 870 for decades. I've gifted one to my youngest. But I still have a couple. And I have a spare barrel. A custom spare barrel. Built for turkey shoots. Heavier than most barrels,, rifle sights, back bored & tuned for sure.
I got this gun from an old friend one day at a turkey shoot. The club was doing a fund raising by selling tickets for an H&R Topper single barrel 12 ga. I bought the last 2 tickets available. I won the H&R. My friend really wanted it,, and offered his custom barreled 870 for the H&R,, if I'd give him $100 boot. I did the trade.
After the main turkey shoot matches,, we'd do side matches,, for cash. Put in $5,, and the pot would go to the winner. I decided to try the "new to me" 870. My first try at it,, and I won the post,, making myself $95.00. So,, I was into the 870 for a total of $7.00. Well, I did try 2 more money shoots,, and lost the second one,, and won the 3rd which was only $35.00. So I always figured I got a free gun, and made $18.00 to go with it.
A week or so later,, my friend wanted to "borrow" that 870 back while his H&R was being customized for turkey shoots. It took me about 7 months to get it back. But it resides here now,, and my friend passed several years later. I fondly remember him when I get it out.
