I had a S&W 586 in nickel that I miss. I don't regret selling it, but I sure do miss having it. I miss a Kimber Ultra I sold earlier this year too. But, missing them is not the same as regretting selling them, so I have no regrets. Situations sometimes require doing what you don't want to do. The only time I've regretted selling a gun was a Bersa 380CC. I resolved that regret by buying another one once I had the means to.
