Help! How do I put this back together?

[Iram]

I just bought a used S&W 910 today. Took it apart to clean, and I can't seem to reassemble it.

I've got the barrel, recoil spring, and guide rod back in the slide. I put the slide back on the frame (pushing down three pins in the back of the frame that stick up), but it won't move far emough back to re-insert the slide stop. No mater how much force I use, the slide won't move back from a normal "in battery" position.

I've tried following this video, but I'm stuck at 1:56. The pins are down, but the slide won't move any farther back than this:

Any suggestions?

Serial number is VCU2### if that matters.

EDIT: With the slide back on the frame (as in the picture above), I can't rotate the safety/decocker onto the "safe" position. If the slide is not on the frame, the safety rotates normally.

cock the hammer and see of it helps

That doesn't seem to make a difference.

The gun didn't come with a manual, but I'm going through the manual for my S&W 908 (which never gave me this kind of trouble) and not finding much.

I can partially insert the slide release, but it doesn't go all the way in and I don't want to try forcing it.

Try checking the position of the recoil spring guide rod if the plunger on the rod hasnt slipped into the hole in the frame may be causing you problems.

either your recoil spring assembly and or your barrel is not inserted square.

Ok, I may be getting somewhere.

I tried re-assembling w/o the recoil spring, and it went on. It got caught for a second in the same place as above, but then slide back (quickly!) when I put a little force on it.

Is there anything obviously wrong with this picture?

It looks like the previous owner actually polished the outside of the barrel. Most of the barrel (except for areas I'd expect to see wear on) has almost a mirror shine.

 

[Iram]

Would it make sense to just replace the whole recoil spring and guide rod?

EDIT: One more picture.

It looks like the guide rod is lined up in the slide, at least to me.

I've got to go to work in about 2 hours, I'm going to take a nap and look at this again in the morning.

Watch this video on take down of the 4506. It's not much if any different than yours. Sometimes you have to take a small screwdriver and gently push that one particular arm down as some seem to be especially aggravating to push down with the thumb nail. I have one like that. Just a gently push is all that's needed if your fingernail won't work. That smallest arm(or pin) is not going down all the way. I have had trouble with my 4506 occasionally with it.

Watch especially from about 3:00 on through the end of the video. It's a good video but a bit out of sink or slow with the video speed.

Thanks. I'm watching it now.

The initial "Don't be stupid" is a great way to start a video.

I don't think it's those pins/arms near the hammer. I've already got to push them down to put the slide on as far as I'm getting; I just can't get it to move back beyond normal "at rest" (slide forward) position.

Iram, is the slide locking lever going in all the way? I just stripped my neighbor's 6906 and I could only get it to go all the way in after lining it up with the slide notch. This notch servers to purposes. First, the locking lever slides into it to lock the slide back and second it allows you to remove or install the locking lever.

Also, the recoil spring notch is the really small half moon cutout on the barrel. It's so small that I didn't believe it would hold the tension but it does.

Take your time you will figure this out.

Let us know your progress.

Ok did you see the guy struggle with the 3rd lever when he was putting on the slide? Maybe that's the problem.


Keep at it....

Turn the guide rod and recoil spring end for end. The small end goes through the hole in the front of the slide and the large end seats in the notch in front of the chamber housing.

 

[kobsw]

Scooter, that seems logical but in this case the small end of the guide rod goes in the direction of the barrel notch.

There's something else going on here.... Thanks for the input though.

Here's a link for disasembly.

No, the lever won't go all the way in. I can't move the slide back far enough.

I've got the recoil spring/guide in the same direction that I use it on my S&W 908, so I don't think it's the direction.

Not to mention, I don't think I could physically get the recoil spring/guide rod installed in the slide backwards.

 

[Iram]

Ok, I just came dangerously close to sending my guide rod flying through the screen on a $2k laptop. I think it's time to take a break from this problem.

Do any of you think a new recoil spring or guide rod would solve the problem?

I tried removing the recoil spring, and I was able to re-assemble the pistol (had to hold it upside down to keep it all in place though). Obviously this isn't a solution, just a data point.

Iram, did you see this disasembly video?

Yup, taking a break is a good idea.

Hang it there.....

Yeah, I think I even referenced it in the first post.

Basically I've done everything in the video, except at 1:56 my slide doesn't go all the way back. I do have all of the stupid little pins pushed down.
