That would be as useless as mammary glands on a boar for coyote hunting.
If it’s close enough to hit with a 9 MM, it’s close enough to hit with a shotgun. See my post in the Predator forum for last weekend’s shotgun result.
If you can’t reach it with a shotgun, you’re going to want something that will reach way farther than a 9 MM. Basically, that will be absolutely worthless beyond 75 yards because there will be so much drop that you’ll have to spend an hour figuring out your bullet drop while the coyote runs away.
JRCs are made for a short range tactical training rifle, especially indoors, and to take advantage of the 9 MM’s low cost. For short range training, there’s not disadvantage, but for anything longer than 50 yards, .223 or better.
