Actually the bottom of the barrel ?

Not sure. Pull the slide back and it slides forward freely....then a little resistance....then a clunk and it goes into battery normally with spring tension. Like the guide rod is suddenly released and slams into the barrel lug. If any of that makes any sense.

What I found is the springs where catching on the barrel when they were compressed and because it is flat spring the edges were sharp and the barrel has rather large O.D. if you take the gun apart look at the bottom of the barrel and see if you have burrs (marks) on the barrel just above the spring.  If you do clean them off in that area with some fine emery cloth or fine tooth flat file with little pressure problem goes away.

Thanks, I'll take a look. BTW, the OEM guide and spring cycle with no problem.

Difference in the guide diameter I think. With OEM the spring has somewhere to go.

EdMC, can you post some pictures of where it's binding? I have not had binding issues with mine when using that plastic washer LW provides, but severe binding issues without it. Mine would bind up near the front of the guide rod, with the spring coils gouging into the barrel. The plastic washer just spaced the guide rod away from the barrel enough that the spring coils didn't touch it.

I wonder if your spring is a larger diameter? When I talked to the ISMI guy back this spring, he mentioned possibly making some changes, don't know if this was one of them, or maybe it's just a tolerance thing?

If you assemble the top end with the spring in place and slide the barrel back and forth by hand, you should be able to see where and why it's binding.

Yondering I do not have a plastic washer on mine either could you post a pic of that setup?

Turned out to be pretty obvious but I was looking inside. The retaining screw of the LW stainless rod is just enough larger than the rod to 'catch' on the front of the slide. And, then suddenly release. Once I take care of that it might work a little better. Thanks for the help, I should have noticed that just from the way it was acting.

You mind measuring the screw head on your LW guide rod?

Maybe this will show it well enough. If I remember how to post a photo.

Thanks.......I got a LW guide with their flat 24# spring and it's binding badly in my LW long slide.

Did you install the nylon bushing?  You'll have LS issues if you don't.  They use to include it only by request  at no extra cost (explained in the fine print, but I haven't purchased one in about a year).

Hard to see in the photo above but the washer is under the screw capturing the spring. My problem is the flat of the screw catching on the end of the slide. Where the rod passes through the hole in the slide when the slide is back and the spring compressed. As the slide comes back forward the screw catches on the front of the slide......on the edge of the little hole under the barrel.

I'd never make a living as a technical writer. LOL I found a photo on the internet of the problem. It's not a long slide ....but the same screw being slightly off center and catching on the slide.

U need the washer.  The spring must have a bad bend at the end for the head of the screw to be that far off.

I suggest calling LWD.  The bushing should center the rod in the hole.  Check to be sure the bushing engages the recess in the slide.  If it doesn't fit, or is a sloppy fit, the bushing or the recess is wrong (either of them too large or too small).  The hole in the bushing should also be a very close fit on the rod.

You know, now that you mention it, I think I had to turn down the head of the screw on my LW rod too, for the same reason. I'd completely forgotten about that. I will check, and measure mine tonight.

I'll post a pic if someone else doesn't beat me to it.

Thanks DM. I got three of the washers when I ordered the other parts. They fit the recess in the slide with the ID enough for an easy sliding fit on the guide. I'm going to just try a cap head screw in place of the screw from LW. Slightly smaller diameter but enough to hold the washer. It was the 'fix' used in the thread I 'stole' the photo from. It cycles manually w/o catching......shoot it later today and see how it works out.

Yondering......the screw head looks like LW had already turned it down some. I'm going to try the cap head as stated above. Maybe I'll get lucky...
