I purchased an M&Pc because it had a thumb safety, one of the reasons I sold it because the safety would dissengage In the holster. It can be modified but I decided to sell it and did not want to modify a gun I was selling.
I believe a poorly designed safety is worse than no safety.
As mentioned above, it's very easy to increase the safety tension by filing lightly and carefully with a needle file in the "V" gap on the safety lever.
It's also stupid-simple to install, or remove the safety entirely. There's zero reason to waste the time and money sending it back to S&W for this.
But, as was also pointed out already, S&W really dropped the ball on this weak,floppy safety design. It's an easy,inexpensive fix, and they have to be well aware of it by now. They should be sending out for free a properly cut safety lever to any customer that calls and asks for one. S&W not addressing this seems like a lazy,incompetent middle finger to their customer base.
They told me I need to send it in so they could look at it the rep also said if I removed it myself it may or may not void my warrantee, No way I am taking a chance at doing that.
Apparently they did not mind wasting their "time and money" having me send it in for them to look at it for them to decide what to do with it, their advice was to send it in to them... so that is what I did !
Well,sure, if they're footing the shipping both ways, then obviously there's no downside there. My M&P9L was bought 2nd hand, so I don't believe they were gonna send me a shipping label, and since the job really is too simple to screw up, I just ordered the safety parts I wanted to install (less $$ than paying shipping to S&W), filed the gap a little, and put it all in myself. Still less trouble than boxing it up, taking it to Fed-ex, and waiting a couple weeks to get it back.
But, whatever works.![]()
The thumb safety is completely superfluous on an M&P. All it does is block trigger movement. If you have the gun in a proper holster, one that covers the trigger, then it is no more safe with the thumb safety than without it.
To remove the thumb safety because it's too easy to switch off is just crazy. That's like saying your spare tire isn't black so you left it at home.
