Glock/M&P striker engagement

[baryon]

Hi Guys,

How much is the striker/trigger bar engagement in a Glock and M&P? I read somewhere that is just 1.2mm on the M&P. M&P looks like a single action. The trigger bar flips the sear at the end of its travel and lets go of the striker. The FPB is already disengaged at this point. Is the Glock safer than the M&P (ignore the trigger pull on both)?

By the way, in a M&P, if you hold the trigger back does the sear stays back also? If that is the case, the striker won't be cocked when it returns back ? I know that the designers would have thought out these scenarios. I am just curious

The M&P has a cam lobe on the bottom of the slide that basically functions like a disconnector. If you are still holding the trigger to the rear as the slide rides forward the "cam" will push the trigger bar to the right and out from under the sear, allowing it to reset and capture the striker and set it for the next shot. This of course also prevents a "full auto" event from occuring. It's a real simple design that is definately NOT double action IMO in any way.
