I have had a M25-2 in .45 ACP, 6-1/2" barrel, for quite a while. It will outshoot most 'target grade' .45 Autos. The pin shooters like them.
Older S&W's like this, pinned and with the nice older Goncalo Alves target stocks and mahogany box, are not that plentiful. I wouldn't take $550 for mine, it's the only handgun I've ever shot five in one hole at 50 yards iron sights.
