Default Model 59 Pin extension

We own a Model 59, Serial No. A357578. We have been firing the unit recently after 18 years of inactivity. We cleaned the gun and it works fine, we fired about 150 rounds through it. We recently cleaned it again and upon reassembly now, (numerous times trying to figure out what we doing wrong), the pin sticks out 3/4 of an inch from the barrel clip.
Please advise.
Thank you

This should be in the S&W Semi-Auto Pistol section as the 59 is that, not an SD or Sigma. Your terminology is such that it's hard to understand your issue, I'm going to take a guess.

I suspect what you're saying is that the recoil spring guide is sticking out past the end of the slide/barrel bushing after assembly. This suggests that you're not installing the recoil spring assembly correctly. There is a flange on the butt end of the recoil spring guide that's supposed to rest in a very slight semi circular groove on the bottom of the barrel when you assemble the various parts. The spring assembly should be held in that groove before you place the slide assembly on the frame.

Perhaps one of our more computer savvy members can respond with pictures showing how things are supposed to look. In the meantime, you can down load an owners manual from the S&W website that can give you some additional guidance. All generations of S&W semi auto pistols use the same system of recoil spring assembly and barrel, only the 39/59 have the barrel bushing as a separate part.

If you're talking about the guide rod - which is the metal rod that the recoil spring fits over - and the front end of it is sticking out the front of the slide after reassembly ...

You're probably didn't sufficiently mount and centering the rear of the rod (the wider rim of the rod's head, or shoulder) in the center of the semicircular notch (shown in the nice pics by the other poster).

When that happens, the spring-loaded plunger in the rear of the guide rod often hasn't found the small round hole in the frame abutment, and/or the rear of the rod has dropped off of the barrel's notch, and the rod can't seat as far back as it needs to seat.

Often, you can grasp the front end of the guide rod (sticking out the front of the slide) ... if it's not too slick from oil ... and twist it with your thumb and finger (and perhaps slightly pull forward) one direction or the other, and the recoil spring pressure will let the guide rod snap back into the proper position.

Easier said than done, sometimes. Just depends how much 'off-center' the rear of the guide became when the rear of it dropped off of the 'assembly notch' before it reached as far back as is needed for normal reassembly.
