Sd9ve slide "grit"

Gritty

In a team effort to try to figure out the grit you feel, I attached some pics of my pistol.

The left pictures are the Galloway 22lb steel guide rod, and the right pictures are the factory 17lb polymer guide rod.

I wonder if the area where the guide rod sits is too narrow, and as the spring compresses its binding on the walls. Or the polymer guide rod is just too weak and its deforming under tension.

Nice pictures.

Has anyone suggested installing the slide without the recoil spring assembly?

Ou1954,Yes, I tried without the spring and it seemed a lot smoother.
Clenceo, nice pics I will have to try this and see. BTW, I sincerely am greatful for the team effort.
With the spring in it feels like its binding on the rear left side rail but it's funny I don't feel it with the spring out.

I'm assuming you have the polymer guide rail? Insert the guide rail like I did in the pics. Or you can also use white out and paint the spring. Reinsert and check where the paint rubbed off. (I believe someone mentioned it)

In my pictures, to me it looks like the spring in the polymer guide rod deflects more than the steel one. If that's your case and if you're able to verify the spring contacting the side walls, head out to your gun shop and see if they have steel Glock 19 guide rods. Ask if you can take your pistol to check functionality.
(it is said Glock 19 guide rod works with the SD series...saw on YouTube...LOL)
Just a thought...

The plastic guide rod has an "X" shaped cross section. Are there any scratch marks on the edges of the "X"?

I think there may be multiple problems because the spring is most likely not gouging the frame as your photo shows. This assumes the rear end of the guide rod is indeed well seated.

You know it takes a second step to get it down into proper alignment after you first get it in.

Looking forward in hearing about your progress and outcome if you come to a solution!

Mush of the grittiness of my SD9VE came from the striker dragging on a poorly machined surface in the slot in the slide. I only discovered this by accident one day while I was putting the gun back together. I used a fine diamond hone to smooth both the slot and the edge of the striker.

While I have no way of determining if this could be an issue with the OP, I thought I'd throw this thought into the mix. It really did make things smoother.

I took it apart and did as clenceo and it looks the same as your pics. I did not noticed any gouges on the rod itself ( yes it is the polymer). I will have totry the white out and post some pics this weekend.

Btw, I do agree that it looks like more deflection with the polymer rod.

Spring Deflection

May not be a factor.

Try the whiteout test and take pictures before and after.

Also, see whether you can get a better picture of the first one you posted.
