Always have a backup, except for last year and I learned my lesson. Last year, I was packing and decided I didn’t need anything other than my Beretta Silver Pigeon 20 ga. So that’s all I took. I mean, its a Beretta, what could go wrong? On day 3 of the hunt during the first walk, the safety locked up. I couldn’t get it off fire at first. Then I got it on safe and couldn’t get it back on fire. I made the first 3 walks that day and just tried to get my gun to work. I finally got it to work but it was sticky. By the last walk, it was working fine again. Not sure what the issue was. I haven’t shot it since. I probably need to take it apart and make sure nothing is actually broken.
This year it was my Marlin Model 90 doing backup for my A5 Sweet Sixteen. Decided to shoot the Marlin and ended up shooting it better than the A5 so the A5 became the backup for the last two days.
