It looks like the trigger assembly on my SW5 needs shimming and I was wondering what is the best way to do it.  I shimmed it with some dense plastic and it is tight, but not real permanent or easy to assembly.

It makes a huge difference on the ejector placement, however when I viual inspect the ejector.

It looks like there is enough meet on the mag well to have the local gunsmith drill and tap a small hole for a set screw.  This would let me adjust the tension on the shelf.  Any thoughts?

Thanks.

Try to use some feeler gauges to measure the gap.

Once you have it then you just have to hunt for the right thickness material for the shim

My 94 required a .040 inch shim, which coincidentally is the thickness of some scrap copper pipe I had laying around. Is currently Barge cemented in there.

Going to make sure that it solves the problem, if so, Barge cement replaced with JB Weld.

Were you having consistency problems with your ejection?  If so, I'm having the same problem with my BW5 and was thinking about shimming it too.

Where in MO are you?

I am in Rolla, MO.

Every so often I get a case that does not clear the ejection port.  Without shimming the trigger pack, the ejector comes up as it should, but there is some gap between the tip of the extractor and the bolt head.  With it shimmed, it comes up much higher.  I have not got to shoot it yet, but I am sure it is going to make a difference based on what I have read about ejection problems.

I'm gonna try to shim mine too and see if it helps.  Do you shoot IPSC up there?  I'll be at C.O.P.S for the Fall Classic this year, may see you there.

I was having some intermittent failure to eject ( low ejector) and recently shimmed the shelf on my Kit built G3.

I used thin bits of metal stuck with silicone to find the perfect height. You can even test fire that way.

I used JB putty on the shelf. First I practiced making a ramp with dumdum putty and a dulled razor blade. Once I could do it reliably I degreased and made a little JB ramp. I tapered it so the housing will snug as it goes on.





On top of that I used a dab JB "two part epoxy" weld and a thin shim cut from a feeler gauge.





It has held up for  a couple hundred rounds so far.

It took all the up down play out of the trigger group. The ejector is almost to the ceiling of the bolt slot. Ejection was less erratic but still not uniform. ( 12:30 - 3:00 )

Thanks for the photos.  I had thought about doing JB weld as well.

If I do anything permanent I will most likely do it to the trigger assembly.  I have a navy SF lower on order and hopefully it will not need shimming.
