I haven't fired one, but have handled one.

I thought the ambi cylinder release was an interesting idea, but it would take some training for me to get used to it.

I didn't care for the trigger, and don't know how hard it would be to tune.

I found the grips too small for my hand, and I'm not sure about aftermarket replacements.

But I think the gun is a good idea, and hope it will be refined a bit.
