AK performance trigger spring, anybody try one?

[snatale42]

I'm at the beginning of a Saiga/AK conversion and while buying my kit I saw this, although I can't see how a trigger spring (in an AK) could give smoother trigger pull I bought it since it's only $10. From what I can see the spring does nothing until it's released and sending the hammer home, but has anybody swapped out springs from the factory braided ones? any difference?

My take, apart from the occasional defective/damaged hammer/trigger spring, there is nothing wrong with the AK "factory" springs. I would not replace a good working spring with this. An AK is an AK. There is not much you can improve on it as it is. It is all a gimmick, like most of the stuff you can buy out there to "dress up" your AK while lightening your wallet.
