Lee's Precision Engineering mag shims

[Fitch]

Wonder if anyone can help here...

Bought a set of the Marui Glock mag shims and despite experimenting with where they go I cant seem to see or notice any difference in using them in any of my mags - which leads me to the question, am I installing them correctly?

I was under the impression they are designed to essentially raise the rubber contact area of the seal with the loading nozzle?

If anyone has added any to their mags let me know how you are installing them effectively and what difference you are noticing.

Incidentally the only mag upgrades I can recommend so far are the purple nineball gas routers you can get - these are amazing compared with the stock Marui ones.

They only go one place, under the gas router.

What problems are you encountering?

I'm quite pleased with mine

The Glock ones are open you see- I mean that they are not a "frame" shape like the other versions, they are a "C shape". Wondering which way the go round you see?

Oh, I assumed they were still square frames!
