I respectfully disagree, I too had concerns after hearing about the flash at night may impair my sight, but before my purchase of the .40 Ported Shield I consulted my CPL Teacher who is a Sheriff and in charge of the arms at the department buying and selling guns for 30 yrs. He told me the flash is so fast it will not be a factor, he does high speed camera photos and claims it is difficult to photograph the flash. So I went ahead a purchased the .40 Performance Center Ported Shield and glad I did, after 300 rounds the flash is not an issue. Actually I think it is cool looking from what I see and I have to look hard to see it let alone blinding me. It is very easy to get back on target with it being ported. As for the comment of waste of good money, it was only $470.00 I thought that was a great price. In short I love it, it looks awesome and I carry it everyday!
