Is it ok to go to the gun range while pregnant?

Probably OK.: Is it the intensity of sound you are concerned about? If so, i believe the baby is well insulated from the stress of high decibel impact. However, it is hard to know for certain, because few studies have been done. There is a cdc study re: prolonged fetal exposure to high decibel sound in working women but the only negative effects were found in women with the additional risk factor of standing.

With safety measures: I'd agree with the prior response about noise and wondering what type of danger one is concerned about. There is a risk of crossing a street. In terms of danger to the fetus, perhaps the most obvious would be lead exposure. Good instructors will teach you to wash hands and thoroughly blow your nose after shooting. I'd assume quite a bit of exposure would be needed for significant risk.
