I’m interested, because I have no idea what it means.
Here is what it means.
“In the 1800s, the phrase “I’m your huckleberry” was used to mean “I’m the one you want,” or “I’m the right one for the job,” or “I’m the right match.” Essentially, it meant that one was up to the task at hand.
In Doc Holliday’s case, it meant that he was up to dueling with Johnny Ringo.”
“look through newspaper archives of the time and you’ll find all sorts of examples of the phrase “your huckleberry,” and they all have the same context: I’m your guy. Or gal. Or sweet potato. Or acre lot near the railroad station. Or pie. You get the idea.”
“The line in the movie, “I’m your huckleberry, that’s just my game” comes DIRECTLY from the 1929 Walter Noble Burns book Tombstone: An Iliad of the Southwest:“Doc, Ringo said, I don’t need but three feet to do my fighting. Here’s my handkerchief. Take hold.” Holliday took a quick step toward him. “I’m your huckleberry, Ringo,” replied the cheerful doctor. “That’s just my game.”

What It Doesn’t Mean
Despite persistent online rumors and myths, the phrase doesn’t have anything to do with huckle bearers, pallbearers or carrying someone’s casket. It sounds cool and is slightly more interesting than the term’s actual meaning, but there isn’t any real evidence to back it up.
And if you use that meaning in the context of the above examples, it makes even less sense. Do you want the best groceries in town? We’ll be your pallbearers!
Val Kilmer even addressed the rumor in his book, I’m Your Huckleberry: A Memoir.
“By the way, despite some fans’ contention that in the 1800s the handles of caskets were called huckles and thus word huckle bearer was a term for pall bearer, I do not say, ‘I’m your huckle bearer.’ I say, ‘I’m your huckleberry,’ connotating, ‘I’m your man. You’ve met your match.’”
The screenplay’s text says huckleberry, Kilmer named his book after the line, and countless newspaper articles use the phrase in the same context. So we can all be the huckle bearers of this rumor and put it in the ground for good.
