Hello,
My 2.0 45 full size is missing the slide stop spring, the long hook spring not the detent one. I can’t find a replacement online. Will the spring off a 9mm slide stop work?

Thanks.

According to this:

Smith & Wesson M&P Slide Stop Assembly: MGW

The slide stops are the same. However I don't see the spring listed separately.

Call S&W Customer Service? Might send you one.

I just sent S&W an email. We shall see what they say.

S&W said that the spring was not called for in my pistol.

I'm a little late to this, but that's what I was going to say.

The spring holds the slide stop down. The magazine follower pushes it up after the last round. Really no need, especially with the 2.0 plunger, to hold the slide stop down.
