    Question about the M&P Slide lock

    I just got my M&P 40c today. I took it home to clean it before I take it shooting. While cycling the gun a few times, I went to release the slide lock with my thumb and I can't push it down. Extremely tight! I have to pull both sides of the slide lock down with my other hand.

    Does anyone else have this issue? I was trying to think back to my other guns so I went to try them out and have no problems pushing down on the slide lock with my thumb to chamber a round. Don't tell me I got a terd!

    You may have a gun with a bit of roughness that will work out with time.

    That said, it is best to practice releasing the slide by pulling it back - in a real high pressure situation fine motor control is likely to fade.

    Blame it on Sixto - now that is a viable plan.

    I had the same problem with my M&P .40 full size. It got easier over time.

    It's really no finer than having to hit a magazine release, or flicking a safety.

    Are you trying to release the slide on an empty chamber? It's going to be harder on empty. It should loosen up, you can sling shot it until then, or if empty, take a little tension off the slide. Try that, hope it works. My 9c is great btw ;)

    Yes my 9c is tight(hard) also, so I just ease the slide , release the lever and then she goes.

    If you have an empty mag inserted it will be harder cause you're fighting the mag spring as well. That had me really frustrated with a PPS until I dropped the slide on a full mag and realized what was up.

    make sure your pushing down (v) on the slide release NOT over and down (---> v ) I know it sounds silly but it works better.... also it will break in in time.. My M&P40 did..... p.s..... love it!!!

    +1 - With an empty mag, especially on a compact, it will take a lot more force. If it's a full mag, you'll have no resistance on the slide lock like you will when the notch in the empty magazine is pushing up on it. Try it with the magazine out.

    If not the case, it'll loosen up over time.

    Yes, the mag follower makes the slide lock release much stiffer. My 4566 is a breeze with no mag or loaded mag, but a bear with an empty mag inserted. Stiff mag spring.

    As far as releasing the slide, I use both the lever and slingshot methods, depending on my mood. My mind is capable of multi-tasking on releasing a slide.

    Yes, I was trying to release it with the chamber empty and the mag in. It won't budge. I have to pull down on both sides of the release lever to get the slide to come forward

    Well this makes me feel better now that I hear it will loosen up with some rounds through it. I'm a little jumpy after having a 709 that gave me nightsweats.

    Thats is why it is not a slide release it's a slide stop or slide catch. It's only real practical function is to catch the slide once your mag runs empty. The Glock the XD and even the Sig's are built the same way and that is way it's best to use the sling shot method to put the gun into battery. The best way to get it to work comfortably both ways though is to break it in but you are right it is tough to manipulate especially with one hand, My duty weapon has thousands of rounds through it and two days ago when doing one handed reloads while holding a shield in my off hand I still had a hard time releasing the slide with one thumb.
