I have an M&P .40c that I carry (nearly) daily. Because my pistol has the mag-drop safety, at the end of the day I usually just pop the magazine out (sometimes not) when I put the gun in my safe. This means the gun usually stays cocked for long periods of time. Is it ok for it to stay cocked for so long? It just seems like an annoyance to unload, de-cock/dry-fire and replace round in the magazine every night but I wonder how it wears on the springs and whatnot under constant tension like that.



Thanks!

I would say it would make good practice to do what you refer to as an "annoyance", unload, de-cock/dry-fire and replace round in the magazine every night. takes like 5-6 seconds and now your positive its safe.

The M&P does not need to be un-cocked. You're welcome to do it anyway, but it's not required and provides no benefits.

The striker spring is always under compression unless the striker assembly is removed and disassembled... When assembled all the springs in an M&P are always under an amount of stress. Springs wear out under dynamic use (i.e. being cycled causing spring fatigue).



Don't worry about decocking the M&P.

IF they had the M&P Anatomy Series Manual they would already know these things.

You don't want to reload the same first round over and over (changing the bullet & case length). That can be more problems than the springs.
