Need Help on S & W 4566

[chama]

I picked up a used S & W 4566 at a gunshow and it has to be the most inaccurate handgun that I ever shot. Shoots low & left and groups like a shotgun pattern. Would a Wilson groupgripper help? Also would adjustable sights that fit a 1911 be suitable for this gun. Anybody have experience this model?
Thanks for any help.

LPA makes an adjustable rear sight that would fit but I don't know that's the problem.

I have a 4586, the DAO version, & it shoots great, like all my other 3rd Gens, even with DAO pull.

SA trigger pulls are usually around 6.5-7.0# on these which may take getting used to compared to a 1911.

How's it's wear? Slide rails? Barrel bushing? Different ammo?

My 4566 TSW rivals some of my better 1911's in the accuracy department. Nothing wrong with the design. How's your barrel lockup when in battery?

Are you fairly new to shooting?

When I first got my 4566 it shot low, I changed the front sight to a trijicon that was taller, that fixed the problem. I understand S&W had several front sights they used depending on the department that ordered them. Shooting to the left is another matter I think.

All of my generation 3 pistols shoot fine right of the box. All are .45 caliber. In fact, I have never added accessories to any of my guns, except for changing a cheap wooden stock for a better one, on a rifle.
