This particular iteration is actually not very common. Relative to the total numbers of M&Ps, not many guns in the very high S-prefix range, like yours, got the new hammer/action before the C-prefix started in 1948.

That is a superb price, even better if you can make this gun whole by finding some sharp-shoulder diamond magna stocks without having to spend extra money.

Keep the hideous rubber grips, though; they are more comfortable to shoot.
