It's really not something I would be worried about - I have an old Brno Model 1 that my Dad bought in 1947 - it can still shoot groups at 25m that can be covered by a man's shirt button - edge to edge (I'm guessing 7mm, maybe). It has had every form of ammunition known to man fired through it.
A quick search shows that glass has been in primers for many, many years, so I am personally not worried.
