Glock 27 auto double tap!

[dragonsden73]

Went out with a friend today to make some noise. My EDC G27...bang, bang, BANG BANG! 3rd pull, 2 rounds fired off. Caught me by surprise....never did that to me before. Wondering if I was just in the right spot on the reset or something else going on? I only have maybe 1000 rounds through it. Put another 3 mags through it after and functioned perfectly. Will give it another shot tomorrow and see if she does it again.

I had that happen with a Zev trigger and spring kit. Try supercleaning the striker channel and replacing the springs.
There can be buildd up in the striker channel, just a little will move the mechanism back slightly, and weak springs dont allow the engagment surfaces sufficient tension to keep the doubles away.
