I've been shooting a 725 in .280 for many years and never had a problem. I suspect it was Remington's quality control deteriorating as its finances deteriorated that caused the trigger/safety issues and the 725 long predates Remington's financial problems. Were it mine, I'd leave it alone.

As an aside, I think the 725 is the handsomest center fire rifle Remington ever built. The checkering on the stock is better than many custom jobs and there is a fair amount of figure in the stock on my rifle.
