I easily belay the Grigri 2 left handed. 15 years ago a petal rep showed me a slightly different technique that works perfectly for grigri 1 and i adapted quickly to gen 2 last year. pm me and I will send you more info.

Btw I use the Grigri in a normal position ( not upside down) and I am female so switching to Gen2 was no big deal. If you have larger hands the smaller size could be a slight issue.

As a fellow lefty, I would highly recommend learning to belay ambidextrously.

I'm Lefty & I reckon in a right handed World one must adapt or die.
Like it ever was.

I can't believe people are so helpless. I am left handed but I live in a right handed world. I can swing a golf club and shoot a rifle right handed. I certainly belay right handed. All this hand wringing is stupid. Stop shopping at the leftorium and take some initiative to learn how to live.

As bearbreeder notes: there are assisted locking and autoblocking devices, but there are no 'auto locking' devices and the idea that there are plays into countless belaying accidents.

I have both climbing technology Alpine Up and and a Mammut Smart Alpine. The Smart Alpine is good, the Alpine Up is great.

If you can't belay just as well with either hand then you haven't yet learned to belay.

There's alot of good advice in this thread about belaying left handed with any device- i've taught many people to belay with the grigri left handed and its almost never an issue. it feels weird for them for one, maybe two sessions, and then its fine.

that said, keep an eye out for the Edelrid Mega and Micro Jul coming out this March or April- $35, 60g (half the weight and almost half the price of the Mammut Smarts), locking assist belay device. Looks and behaves like an ATC except when you fall, then it does the locking assist thing. Pretty neat little device.
