A little research on Glocks and most striker fired pistols show the striker is in a forward position resting against a block and does not travel rearward until the trigger is pulled. The Taurus SA/DA is truly SA as the striker is always in the "cocked" rearward position unless a failure to fire occurs. The Taurus like a Glock does have a block that doesn't drop out of the way until the trigger is fully pulled. Glocks and most others would be considered DAO or DA/SA.
No, that isn't really true. The Glock is the closest to a double action pull with it's "safe action" that does move the striker back but it still isn't even clear that it's striker, if directly dropped from it's "cocked" resting position wouldn't activate some primers. The other guns, the XP and the M&P move the striker a miniscule amount backwards...no more than many SA guns move a hammer back when the trigger is pulled. They, in no way could be considered as safe as a real DA action which raises the hammer completely from rest and drops it.
The main reason these guns like to be thought of as DAO is because police forces and ignorant owners, are willing to carry a DAO gun without a safety, but not an SA gun.
A good example of an SA gun, that has more rearward hammer movement, in SA mode, is the CZ40B. The CZ40B, in SA mode, moves the hammer backwards farther, and has a higher stock SA pull than the S&W M&P.
I do think a safety is a good idea on an SA gun that has very little trigger travel and a low trigger effort, such as a 1911. However, if one considers the 5lb trigger effort of the S&W M&P, and it's short trigger travel, to be a sufficient safety, than one must conclude that the 5lb travel and considerably longer trigger travel of the Taurus Millenium is also safe.
...video might be seen by just the right idiot or careless individual, and it might just stick in thier head enough to save someone's life.
This video is much more likely to help a lawyer sue Taurus than help prevent an idiot from shooting himself with the gun.
A person would much better be served by watching this video on gun safety.
