After shooting , I always pull the trigger assembly and let the hammers down gently before putting the gun away.
Today, when I let the hammers down, the first one (lower barrel) felt much weaker than the second one. I put on my reading glasses and saw that the weak one had a hairline crack in it.
I bought the gun new, for shooting doubles, and it now has about 19,800 shells through it. My question is, since there is about 10,000 shells on each spring, would you replace both springs, or just the one with the crack?
