Well, some launchers have trouble firing certain grenades due to the actual hammer that fires the grenade, mainly an issue when firing some of the CO2 grenades out there. As far as I know, it's only an issue on the older launchers, but... it's a bit unclear in the first place.
Also, I'd point out that fit is something to consider with any 40mm launcher. While normally only an issue on the M79, KA grenades tended not to hang on the breech very well and could fall past the extractor, creating a pain in the a$$ to remove. On an M203, the main thing is that long grenades will not fit, one reason a lot of militaries are going to the Hk AG36 and EGLM launchers, which load off to the side.
But, try out the brand of grenades you're planning to work with in the launcher. I don't expect anything to crop up, but better to find out before you buy it.
