Default LG300 Dominator Air Leak?

A friend asked my opinion on a s/h LG300 Dominator FT that he was thinking buying. He's a lefty and said because of the way he holds the gun he could feel a slight puff of air coming from the dry-fire/safety rocker switch when he fired it - and did I think it was right. I tried it and confirmed that I too could feel it. My opinion was that there should be no escape of air from anywhere other than the muzzle, but as I'm not familiar with the gun I thought I'd ask you guys for an opinion.

I'd say this is possible and not something preventable.

On a dommy the air passes past the valve which is sealed past the seat and then up to the transfer port. But the valve stem is not sealed and it's possible for air to get past that to the dry fire wedge which is also not sealed.

However it's not something I've noticed on mine. That said mine is removed and taped over. It can also escape via the hole to the left of the pellet channel as this is also not sealed.

What I would check though is that your breech is sealing. With a pellet in the gun, close the breech and put a small piece of single layer of tissue on it and fire. It shouldn't move, but obviously check it's not the dry fire.

Or you can use talc with a small brush.

It is normal. it is the air that escapes from the hammer cavity. When the hammer goes forward it pushes the air that's in front of it out through the safety.
Nothing to worry about.

Probably a bit of what Sven said and also a puff of high pressure air escaping down past the valve stem .
Normal . Don't worry
