IANAP, but here's my simple analysis: the schartzchild radius of two collided protons would be about 5e-54 meters, which is about 1/3 the radius of a single electron. The gravitational pull of this tiny blackhole would be the same as two protons (ie, almost nonexistent for our purposes). I'm not sure, however, whether the singularity would carry any charge.
