S&w m&p 9mm

While at the range I disassembled my M&P to check for excessive barrel leading, I reassembled it (possibly wrong). I installed a loaded clip, loaded a round and it would not fire nor could I retract the slide more than about a 1/4 inch. When at rest the rod protrudes about a 1/16 inch out of the slide. Any suggestions on how to free the slide?

Thanks in advance

I don't think anyone's going to touch this.

You want suggestions on how to work on your loaded pistol that's all jammed up?

My suggestion would be to go see a good gunsmith.

Not trying to be smart. I just really think that's your best (insert safest) option.

With the gun being in a bind and LOADED, don't mess around. Take it to someone qualified who, hopefully, knows what they're doing. I have gotten guns in binds like that before, unloaded thankfully, and it's a pain. Seriously though, don't mess around with a loaded round in the thing.

Stuff like that scares me...

And if it fires, he blows a nice hole in his hand IF he doesn't shoot anything else. I agree with the others. If he didn't have enough knowledge of its workings to keep from assembling it incorrectly, he should take it to a gunsmith. DON'T mess with it on your own. Also, when he fixes it see if he can give you some insight on what went wrong and how to avoid it in the future.

I'll be interested in hearing what went wrong since I have a 9c.

After reassembly did you dry fire it? Did it seem to cycle properly?
When you say "at rest" is the slide lined up in what would be battery position, or is the slide "jacked" back that 1/16?

Good luck.

That would put your hand in front of the muzzle, bad idea.

If he pulls the slide back it won't fire. That gun fires by the trigger action cocking the striker and releasing it. It won't fire unless the trigger is all the way to the rear with the slide in battery.

Sounds like you didn't seat the recoil spring/guide rod properly....remove the mag, lock the slide back, verify the firearms is unloaded, disassemble the gun, make sure the recoils spring/guide rod is seated all the way next to the barrel and put it back together.

Sounds like a problem with the bullet diameter. Lead bullets being slightly larger than their jacketed bretheren and all but that fails to explain why it will not fire.

The M&P will fire slightly out of battery so even if it were loaded long it should still go. There is nowhere for the guide rod or recoil spring to go inside and being captured even a broken, flat wound spring would still be wound around the rod (unless that broke).

At full battery (rest as the op calls it) my Full Size and Compact guide rods both protrude about 1/16" and the Long (5" barrel) is recessed such that the slide would be nearly 3/4" rearward for it to protrude. I'll guess the op has a fullsize or compact.

As the slide moves rearward about 1/4" the frame catches the barrel and the slide interfaces with the chamber shroud (that beveled area on top where the finish starts to wear first). nothing much to catch on...

If the trigger did nothing, it could be the op has a mag. disconnect safety and did not fully seat the magazine. After chambering a round the mag. could have slipped down and engaged the sear disconnect. The next round could have interfered with the removal of the first or it could have been a tight round (coupled with the above) that simply stuck. That would account for the weapon not firing and the inability to remove the chambered round.

It's all guess work at this point as we don't know the particulars. Did he remove the "clip"? (to the op that's a magazine), did he handload? (not aware of any commercial lead ammo (unjacketed) for the 40cal. I suspect the problem is easily remedied in the end but past his skill level at this point, no offense. What is known for certain is that the op has a dangerous situation, especially on a Sunday when no smith I know ever works.

Maybe a PM to 9mmepiphany could get the op through the situation safely.

I"m aware of how the weapon functions. The point is that the weapon is locked. He already stated that he can not pull the slide to the rear. I'm also assuming he has a limited understanding of how the weapon works or he wouldn't have made this mistake. If you would like to suggest that he handle the weapon with his hand in front of the muzzle good for you. I think it is much more sound advice to advise him to seek better help rather than hoping that when he is tugging the slide around and wiggling the guide rod that he has enough presence of mind to keep his finger off the trigger. If your advice works, and he has his finger on the trigger when it snaps into battery, he WILL shoot himself in the hand. There is NO chance he can hurt himself by taking it to a professional. Its better safe than sorry.

Guys,

The op has been contacted by a Moderator in private, no word back yet. Let's all hope he's ok and put all the speculation (mostly mine) to bed for the night as we wait for what is hopefully a safe resolution. Certainly a teachable moment about RTFM. (read the freakin manual)

The OP is off-line

Regardless if it was assembled with the rod incorrectly seated (my first thought) or round not fully chambered (makes sense too) or a combination of both, we need to be careful with the advice we offer.

We have no idea of the OP's experience with this gun or any gun, where he'll point the muzzle or place his fingers...it is always safest to take the lowest common denominator as the basis of offering advice when dealing with a loaded weapon. I would certainly not advise he wiggle the guide rod

Without more information, I'd also recommend he take it to a gunsmith or maybe a range master/armorer.

If you are aware of how the gun functions, then you know the gun cannot fire without pulling the trigger completely to the rear. He said he can pull the slide to the rear approximatdely .25". That is enough to engage the disconnector. Also, you can wiggle the guide rod with your fingers being clear of the muzzle by approaching from the bottom. That's exactly what a gunsmith is going to do.

and if you are still afraigd the OP is going to blow off his fingers, a set of taped over pliers can be used to manipulate the guiderod, thereby keeping the fingers well beyond the reach of the bullet.

Please refer to post #12

without knowing more, I don't think it is a good idea to recommend he try anything that will place the muzzle anywhere except pointed in a safe direction...away from him

Some people are so full of their own wisdom they think that any advice they give HAS to be right and if someone follows their advice there is no chance they could hurt themself. Personally, I would rather err on the side of safety.
