Title: My Glock 20SF LW Longslide locks all the way back on every round
Post by: Pablo on January 30 2016 11:51:11 AM MST
It's not right, the slide lock isn't engaging, it actually wedges back. I just nudge it with my weak hand and it pops into battery position, round feeds and fires just fine. There is a tight spot in the slide toward the front I think.

I'm running an 18# Wolff spring. A 20# spring is too much spring. I could try my 19# spring, but I want to fix this issue.

Ideas?

Does the slide move back and forth freely without the barrel or recoil spring?

Is the front of the slide getting caught on the spring recess in the plastic frame? I have seen pictures of the front of the LW slide where the recoil spring rests, and it doesn't look like the stock Glock slide.

When the slide is stuck at the rear, is the barrel loose or tight? I should be loose.

And...

Can you hang it up manually by pulling the slide all the way back?

1) Yes, without barrel and spring slide glides nicely.

2) Yes they are different. I can't see where it might be rubbing

3) It's  a bit loose, but it's like a mouse trap. I touch it and that massive slide come slamming back. I comes free with just a touch.

Yes. But it takes 10mm force and quickness.

The LW slide is contacting the inside of the frame, and as mentioned is just a slightly different shaped and is just wedging, I mean barely. But enough to hold the slide, and then release. I tried the original Glock spring first, last year, not enough spring, and I'm sure it made a wedge place, then I was running a 20# aftermarket, TOO much spring (and of course never noticed any wedgey).......so I bought the 18 and 19# Wolff springs and rod. Perfect feeding except this problem.

I think I could have removed some material to solve the problem but then I remembered from my earlier Glock days I have a Lock and Lock storage container of Glocky parts. In there are the  infamous do nothing Strike Industries Shock Buffers. Both a red and a smoke/black one.

Slap the red one in. Problem solved. Plus I like the way it works with the free Wolff guide rod. Win-win. If the red one gets all beat, then I'll try the smoke one or remove some material. But it looks pretty hardy.
