I own one Taurus a 445
It does not have the lock and I would not have purchased the gun if it had.
I hear every one say "There not a problem"
But they only have to fail once.
I like the 445 that I own, its been a good and dependable gun but it hasnt fired that much. I bought it on a wim (I have a thing for 44 sp)
I will not purchase a gun with a lock, its only added by and becouse of lawyers.
That is the only reasion that builders are putting them on guns, the ONLY reasion.
I dont feel this way just about Taurus but all manufactures.
"KISS" I live by this rule
Keep It Simple Stupid
And putting an internal lock on a gun, any gun is,,, well you know where I stand.
If you feel you must lockup a gun, get an external lock or a safe.
