S&W 659 Question

[miller_tyme042]

I recently bought a S&W 659 9mm 2nd gen. but it did not come with a manual. Can anyone help explain how to break it down for cleaning? How do I release the slide? Thanks

I owned a 5904, but this "second generation" pistol should be identical in takedown. Remove the magazine and be sure the chamber is unloaded. Pull back the slide until the slide stop notch lines up with and over the front rounded portion of the slide stop lever. While holding it in this position, push out the slide stop (a small nub will project from the right side of the frame) from right to left. It may not push out with just your fingers; you may need to tap it with something like the butt end of a screwdriver handle or other similar non-marring object to get it started. When the slide stop lever is removed, release the slide in a controlled manner and it will come off the frame. Remove the recoil spring and barrel from the underside of the slide, taking care to note where the recoil spring guide seats on the barrel. When reassembling, the ejector and magazine safety lever will have sprung up slightly. You have to push them down before the slide will go back on. Reverse the initial procedure to put the slide stop back in and complete reassembly.

Try a search on HR, the Firing Line, and Glocktalk. I've posted it before for S&W autos. (3rd Gen S&W autos will not have the barrel bushing.)
If you can't find it, here it is:

1) Remove the magazine.
2) Check the chamber. Make sure it's is empty.
3) Check the chamber. Make sure there is no ammo in the gun.
4) Check the chamber. Make sure the chamber is empty.
5) Did I mention to make sure the gun was unloaded?
6) Collect all the ammo. Place all the ammo in a ziplock bag. Take the bag with all the ammo in another room. Place the bag in a drawer. As you leave that room close the door. Do not return to that room until you are finished.
7) Return to the room where there is no ammo and which is now unloaded gun. Check the gun again to be sure it is unloaded.
8) Place the safety/decock lever in the 'fire' position (it should be pointing same direction as the barrel).
9) Notice where the slide lock/release lever is located on the left side. In front of the lever is a notch in the slide.
10) Pull the slide to the rear to where the notch in the slide is lined up with the front of the slide lock/release.
11) With the notch lined up with the front of the slide lock/release lever, from the right side push in the slide lock/release lever (small 'button' above the trigger).
12) This should move the slide lock/release lever out to where you can remove it rest of the way from the left.
13) Once the slide lock/release lever is removed the slide can be slide off to the front of the gun.
14) If the hammer is cocked, while removing the slide hold the hammer so it does not slam forward. After the slide is cleared let the hammer go forward to the at rest position. Do not dry fire the gun with the slide removed. The hammer banging on the frame can crack the frame at the point of contact.
15) When removing the slide cup your hand around the slide so the spring/guide rod doesn't fly off. It's under some tension.
16) Lift the spring/guide rod out from the rear where it should be engaged in a small slot in the rear of the barrel.
17) Rotate the barrel bushing about 1/4 turn and remove it from the slide.
17) Lift the barrel out of the slide. You may have to giggle it a bit but it should come out easily.

That should be all you need to field strip the 2nd Gen S&W autos. To reassemble:
1) place the barrel in the slide. It should be fully mated and locked into the slide.
2) Place the barrel bushing back in the slide around the end of the barrel, and then turn it so it's lined up.
3) Place the recoil spring back on the guide rod. Insert the spring into the hole under the barrel.
4) Compress the spring and place the guide rod end (with the small plunger on the end) so it barely catches on the notch on the bottom of the barrel. That should hold it in place. Be careful tho, the spring is under tension. Don't kink the spring when you compress it.
5) Align the slide with the rails and place the slide back on the frame.
6) As the slide gets to within about 1.5" of being completely on the frame you'll notice 3 small levers sticking up from the top of the slide in front of the hammer. Push down each of those levers as you push the slide further to the rear. Sometimes the slide will seem to catch and won't go further. It just takes a bit of giggling and persuasion but it will eventually go on smoothly. You should not have to force it.
7) Push the slide to the rear far enough to line up the notch in the slide with the front hole where the pin part of the slide lock/release can be inserted.
8) Fully seat the slide lock/release so the rear of it is in the rear notch.
9) Perform a function check. Remember that the hammer will not drop by the trigger unless there is a magazine inserted. If you want to try the trigger action be absolutely sure the magazine is unloaded before inserting.

Thank you to all that replied.

I was able to successfully disassemble, clean and reassemble the S&W 469.
