Glock 17 Gen 4 Extended mag release issue

[Henry The Yellow Dart]

Good day,

Recently purchased an aluminum extended mag release from GlockStore for my Gen 4 Glock 17. The magazine will consistently eject after firing one round from the gun.

I tried firing with my right hand only in case my support hand was applying pressure to the release but had the same results. I have re-installed the stock release but haven't had a chance to range test to make sure it works (though I don't expect any issues).

Just for added info I also installed a Glock extended slide release as well.

Has anyone else experienced this or other issues with aftermarket parts?

I would first check that the spring has seated properly in the groove then secondly, make sure the catch is machined properly.

It should look just like the stock one where it engages the mag.

A few pics would probably solve all.

Let us know.
