Nice thread! I have one that was my Pa's and have shot it to death. You have a fine model ten there.
ZVP my brother had a 586 smith years ago that he wanted me to try out, he complained that it was rough and gritty. He was right. I asked if he minded if I could shoot it extensively, he said yes I could. So I had it for 4 months, in that time I shot it almost every day, making ammo as well every day. It was a good gun, when it was time to return it to him he could'nt believe how smooth it was from when he had last handled it. He asked what I had done to it, and I told him I shot it alot. They get better with time and shooting. I had a Ruger GP100 that was like that too. It was much smoother 3 to 4 thousand rounds later.
