Smith & Wesson M&P40 question

As far as I know there is nothing to fix, op if it bothers you that much you may need to consider another gun thats what my wife did when she had a m&p9 and if I remember it even mentions it in the owners manual.

Correct, there is nothing to fix, I depend on this action for action shooting and have never had a FTF. Every one of my semi's allows my slide to go forward when forcibly inserted into the pistol. If you don't want the slide to go forward don't force the mag in.
 
I do not depend on this for action shooting, not concerned with saving a second for the timer. The mag goes in hard every time because I do not want any doubt that it us locked in place and I manually rack a round because I want to be 100% that a rounds is chambered. I just don't like the idea of having that live round on the ground and not in my gun.

Anyways sounds like there us no fix so I will continue to use it as I have been.
 
This has never happened to me. If it worries you, there is a loaded chamber indicator and you can perform a press check if you are so inclined.

No offence but checking the indicator while the pistol is in use does not seem like a good training tactic.

Edit: As I said earlier it has happened to me a couple times thus I ask the question if it can be changed.

Wondering if there is a mod I can do or a smith can do to stop the slide going forward on its own when you hammer charged mag in? M&P is a fine pistol but I think this has got to be one of the worst features on a pistol I have seen.

If a pistol didn't do this I would be concerned.
you cant try this though: hold the gun straight up and down when you feed the mag.
a slightly canted gun with a mag being sent home should drop the slide for you. Beretta, Sig, Glock... they all do it.
sometimes, seconds really do count.

I was unaware that other makes of pistols also did this. I will try the pistol straight to feed the mag on Monday and see if there is a difference, I usually do load on a cant.
 
Maybe the mods should shut this thread down. I have my answer to the question that was actually asked about the gun itself. Wasn't really looking for advice on how to shoot or opinions on whether I should buy something different.

lowering the gun to below your line of sight, (while maintaining the muzzle in the direction of the target) look down on the gun and you will see brass, or not.
No offense to you, but for your confidence and proficiency with a pistol I strongly suggest you seek some training.
Knowing if your gun has rounds in the chamber while is use is very important, and its a built in feature of the barrel.
You need to become more comfortable with your gun!
cheers

No offence taken as you fundamentals and practical uses for a firearm may not be the same as everyone's! I think I am thinking about this differently then you guys are. I perhaps use this pistol for different reasons then range toys or competitions and there is a reason I would not want to bring the gun into me and look down at it if I am reloading.

And to be clear I know for certain there is a round in the chamber every time I reload because I manually chamber that round so that I know 100% it is in there. Perhaps whatever 'training' I have received may possibly be different from yours?

I personally like this feature as well. I bet you could defeat this issue by filing the slide stop notch to have a more positive angle of engagement. Looking at my slide i can see here that the slide stop notch is not quite 90 degrees. If you filed it to 90 or slightly more I bet it would do the trick. Might make it tougher to drop the slide with the slide by pressing the slide stop though.
 
I wasn't going to reply because per OP's comment, it's already a dead horse. However, one should know that, if the auto slide lock/load cannot be trusted, so as your manual load. As mentioned in any manual that comes with your gun, there is always a warning from manufacture saying that Never solely rely on any particular gun feature because they all might fail as it's mechanical.
A real example is today when I was at range with my sr1911, after manually pull the slide, the round did NOT load. I knew that because right before raising the gun to shoot, I always take a quick peak on the loaded chamber indicator. Once I unloaded the mag, I found the round was stuck in the mag, maybe I didn't put it properly. Once re-sit it, everything was fine.
This tells you the same thing others are trying to tell you. The only thing you can/should trust is yourself. make sure you develop a routine that covers all possible faulty situation.

ok, curiosity kills the cat.. but I would like to know the reason.
I am now visualising someone with a pistol in their strong hand and full extension, trying to load it at arms length, who will not bring the pistol to their chest; enabling them to look down through the cut in the barrel to let them know if the gun is loaded or not.
I am visualising someone handling their pistol like it was a stinky diaper.. hold it way out there at all times.
The M&P .40 was my duty gun. Im not a competition shooter, I guess my style of shooting is what you would call "defensive".
I could try and send you a copy of the participant handbook from the M&P40 transition course.
