Well, yes, I think there is.
I'm going to recommend a set of gunsmith's screwdrivers, although if this is the only screw you're having a problem with the solution is a bit expensive.
Brownell's, among others, sells gunsmith tools. Chapman's is a good quality set and it should contain the one you need. I would imagine you can find a smaller set for less money, but this one is a good assortment, so the odds of it having the bit you'll need are quite good.
Also, if you're not already doing so, consider using some thread anti-seize compound on the screw threads. I use Thompson Center's Bear Grease - there are lots of good alternatives.
