I got a Taurus 941 (B2UL) a month ago and ordered the Taurus mother of pearl grips which came the other day. But, the pin bolt from my stock grips are too large for the pearl grips. I've been calling Taurus customer service all day and can't get anything except a recording even though I held for half-an-hour early this morning. Should I risk drilling out the hole in the pearl grips? Has anyone else encountered this problem? Thanks.
