If these pins are at full protrusion, then you may have the issues you mention with certain ammunition and/or certain primers.
I would have a good double gunsmith slightly shorten (not much) and round the right pin to hemispherical. The left looks better, but might stand a bit of rounding, too.
You might also avoid import primers. These tend to have thinner caps which pierce more easily in older doubles. Cheddites are notorious for this in some guns.
Remember... get a GOOD smith to do this job right.
