Close. It was the second Death Wish. And your quote came from Unforgiven when Clint Eastwood went into Skinny's bar where the body of Morgan Freeman was on display after being killed by Little Bill. "He should have armed himself if he is going to decorate his saloon with my friend" Or something close to that.
Dad: “What’s important?” Son: “To hit the target.” Dad: “When?” Son: “The first shot.” Dad: “Why?” Son: “Because I might not get another.” Hint: December 1953 Sweetheart Edited to add Hint #2: The Salmon River
I think I just watched this one ... and can't for the life of me remember. The Magnificent Seven? (watched it a few days ago again) So I'll offer: "How'd you collect all those Purple Hearts? Your rifle blew up with you?" (for those who watched the Veteran's Day movie marathon on TCM and AMC)
Sergeant Farrell from science hill Kentucky, Edge of tomorrow “where’d you get that pretty little gun?”
To Hell and Back with Audie Murphy as himself. Edit: Here's mine: "Survival kit contents check. In them you'll find: one forty-five caliber automatic; two boxes of ammunition; four days' concentrated emergency rations; one drug issue containing antibiotics, morphine, vitamin pills, pep pills, sleeping pills, tranquilizer pills; one miniature combination Russian phrase book and Bible; one hundred dollars in rubles; one hundred dollars in gold; nine packs of chewing gum; one issue of prophylactics; three lipsticks; three pair of nylon stockings. Shoot, a fella' could have a pretty good weekend in Vegas with all that stuff."
Gettysburg. That's a line from Jeff Daniels' character Col. Chamberlain. Here is mine: "Folks back home say I learned to shoot before I was weened. They's exaggeratin' a bit though."
Dr. Strangelove, or How I learned to Stop Worrying and Love the Bomb - Major "King" Kong. How about: "I found out early that most men, regardless of cause or need, aren't willing. They blink an eye or draw a breath before they pull the trigger. I won't."
It's definitely John Wayne. But I couldn't quite place it. I had to google it. As such, I won't post the answer and leave it for someone who knows it to answer. Good movie though. Speaking of the Duke, here's one: "Touch that gun and I'll kill ya."
