Go best gun意思

"Go best gun" is not a common phrase in English and it's not immediately clear what it means. It could be a colloquial expression, a term from a specific context (such as sports, gaming, or military), or a typo/misunderstanding of a more common phrase.

If you're referring to "go big or go home," which is a popular saying, it means to do something on a large scale or to the fullest extent, or to give it your all, or to not hold back. It implies that it's better to aim high and take risks than to play it safe and potentially regret not trying harder.

If you're referring to "go for the best," it means to aim for the highest quality or the best outcome in a situation.

If you're referring to "go all guns blazing," which is a phrase used in the UK, it means to attack or proceed with a lot of energy and determination.

If none of these interpretations fit the context you're referring to, please provide more information so I can better assist you.
