Removing bolt pin on Model 41 slide
Tried to remove pin today and used flat punch and hit pretty good with no results. Anyone seen this before. This is a 88 model in good condition. What specific punch should I be using? thanks jim

Some guys use a solid Brass punch, but I don't for this particular application. It is too soft and does not work as well on very tight pins as a good steel one will. The Brass will not deform the pin however it will leave a gold mark on it that you will have to remove. If your Steel punch is smooth and burr-free, 99% of the time there will be no visible deformation, loss of blueing or marks transferred to the pins finish. Brass on the other hand almost always leaves behind a tell-tale mark. While I do have a Brass punch set, I rarely use it anymore. AGAIN - if using Steel, remove ALL burrs and sharp edges prior to use. Some here might not agree with me, but it works very well for me.
I use Starrett Steel punches and make SURE they are smooth and burr-free prior to use. Also another very important factor here is that you have a good Bench Block that will not absorb the energy or allow movement - that will result in more hits to remove pin and probably more deformation. I use a home made Hockey Puck Bench Block and when that one absorbs the blow too much, I use a Starrett Steel Bench Block with a protective sheet of paper to protect the guns finish. It also helps of you have someone around to securely hold the slide down when you strike the Punch - unless you have three hands.......

The link below has some maintenance tips. Remember the pin has a head on one side....if you are looking at the slide from the back, it has to be driven out from right to left.

Hey Guys,
Sorry about bringing this old tread back to life. I am having this exact problem with a recent model 41 performance center.
For the life of me, I just cannot remove this pin. A bit of knocking moves it a tiny amount. When I try to push it back, I hear/feel a click. Like its captive somehow. I even called S&W and they said there is no trick to it, it should just come out.
Would appreciate some guidance. Otherwise, I would have to find a decent gunsmith here in NYC area, which is a very difficult task. My only other option is to mail it back to S&W, which would be a huge pain in the @$$.

Remember that the pin has a cap on one end, so it has to be driven out from right to left. (when looking at the slide from the rear)
Also, if you look at the end of the pin (with a magnifier) where it is exposed on the right side, the end of the pin is swaged. This is done after assembly so that the pin will not come out or "walk" out during firing. (in other words, it is "captive")
As Chief38 pointed out, the secret is using the correct size, (diameter) high quality punch and hammer, with the slide backed up by a non-marring but unforgiving bench block.

Thanks very much for responding.
I am trying to replicate this exactly.
Going from right to left and using a 1/16 straight punch with non marring tip and this bench block as backing. https://i.ebayimg.com/images/g/SvUAA...Q-/s-l1600.jpg
Still wont come out. I hate to take it to a gunsmith due to failure to remove one pin. But, that sounds better than damaging the slide.
Still, this is bothering me a great deal... How difficult can it be to remove one pin!?
