FTE Issues

[KahrMan]

So I finally had some time to go to the range this weekend.  I needed to sight in the Holosun on my G48.  

This is the first time I have shot this gun since I bought it.  Right off the bat I started having extraction problems.  I would have 3-5 failure to extract per magazine.  

Only had one brand of 9mm with me but did try several different magazines but nothing helped.  I was able to shoot it enough to get the Holosun zeroed.  Now I just have to figure out the extraction issue before I carry it.

 

So I get home and take slide off.  I start inspecting the extractor to see if it is chipped or broken.  As I am rubbing it with my finger I notice it is loose.  I can move it.  Stripped my other G48 to compare it to and as expected the extractor is nice and tight.  So time to completely disassemble the slide.  Pull the back plate off and take out the firing pin.  Start to pull the extractor rod out but it will not come out.  The spring pulls off the end of the rod and just the nipple the spring attaches to is sticking out of the channel.  Gently grip it with needle nose pliers but it will not come out.  

As I am sitting there staring at it I realize that the right screw for the Holosun is directly over this channel.  I back the screw out a couple of turns and the rods falls right out like it is supposed to.

So it looks like the screw was not allowing the extractor to move freely.  I checked and I did not have any shorter screws.  So I got my dremel out and very carefully started grinding down the screw.  Now the screw is in nice and tight and does not effect the movement of the extractor.  Hopefully this fixes my problem.  Now I just have to get back to the range and shoot it some more.

Glad you got it figured out.  I’ve seen extremely worn Glock extractors fail, but not new ones.  Are you using Shield mags/mag catch on this gun?

Shield mags but not the shield mag catch.

Apparently folks are having to shorten the optics mounting screws provided by Holosun so that they don't impact the extractor assembly.

I saw this mentioned elsewhere recently, and I don't recall where it was.  Probably Facebook or Reddit.  I'll see if I can find more info.

I'm still searching but I did find this on YouTube.  The fix is to take out the optic screw on the ejection port side and file down the length of it slighty.

Thanks.  The Dremel with a grinding stone took care of that yesterday.  I just need to get back to the range and verify if this fixed the issue.

I should really read more carefully.  I would have seen that you solved it.

I remember buying mounting screw from Battlewerx when I fitted my G45 with a Holosun. They do a whole range of screws for different applications.

Ain’t it a good feeling when you can solve an issue like this yourself? I know I usually enjoy what few times it’s happened to me.

Grinding down the screw a little fixed the issues.  Ran a bunch of mags through he G48 today and not one FTE.

Yes, I had to shorten them on two Holosuns.  Too bad they only supply one set (long),

The Holosun 507Cx2 I just bought had two different sets of screws—long and short included in the package.

Wow, not like mine,
