    I have owned my M&P for about six months. I have experienced two rather annoying issues. The first is the fact that when I insert a new magazine when the slide is locked open it automatically chambers a round. Secondly, during my last range trip I had a double feed. (One round in the chamber with the second right behind it.) It has had only a few hundred rounds through it. I am considering trading it for a XD or XDm 9. I also have a Glock 19 and love it! 1200 rounds and counting with zero malfunctions! Any thoughts and opinions would be appreciated. :)

    S&W has a lifetime warranty service and covers shipping expenses to and from the factory. Simply return the M&P for service. Give them a call (Toll Free Number) and they’ll send you a prepaid shipping label. Enclose a letter noting the discrepancies. I believe that currently S&W has a shipping agreement with UPS.;)

    I count the slide closing on an inserted loaded magazine to be an advantage. Saves me a little time on the slidelock reload required in IDPA. This is actually more common in Glocks than S&Ws.

    A double feed - caused by a failure to extract - is an unfortunately common flaw in the Plastic M&P. Send it back to be fixed.

    i happen to like the slide closing upon insertion of the mag too...i hope the one i'm getting does that.

    the double feed does sound like the extractor...maybe you didn't get one with the updated 9mm extractor. the M&P 9mm and .40 were using the same extractor which was optimized for the .40

    these issues are not unknown to the MP9.

    although, it's generally not seen as an "issue", i do not like the automatic chambering of a round. i prefer to control that action myself. a new slide stop/spring should take care of it--unless the slide stop notch in the slide wasn't machined properly. in that case only a new slide will fix it.

    the double feed prob is caused by the extractor. s&w will take car of it under warranty.

    This isn't a big deal as long as the round does chamber. But I would rather have control over it.

    This is bad. A double feed is the worst stoppage you can have in an auto pistol. Failure to extract is usually caused by an extractor problem. Lock the slide back or remove it and examine the extractor claw for being misshapen, dinged, chipped or broken. If this is good, clean the extractor's tunnel through the slide thoroughly by flushing solvent through it. Binding in this area will cause the extractor to not slide deeply enough into the case groove and slip off.

    the double feed may be an issue, i would shoot it, and try it out a little more before i got rid of it.

    the slide going foward when a new magazine is inserted is common on several handguns. you can even use it as an advantage for a speed reload if you train on it in your routine.

    That's why I'm thinking of trading it for an XD or XD-m. If I didn't already have three glocks I'd get another.

    You are entitled to my opinion.

    i've owned two, and i wouldn't say they're junk. they definitely need some mods though, no question about that. i still have my glock, which is a far better weapon.

    m&p's are a nice first step in an evolutionary path.

    I have problem with that. For me personally I could not or would not trade off a firearm with a known operational defect with out correcting problem or pointing out the problem to the perspective buyer.

    Yes we may have to simply agree to disagree to maintain civility.

    this is true. i kept waiting for S&W to take that step before buying one...i guess they are selling to many to make it a priority. however i have found the next step, Apex Tactical is currently offering a tool steel sear, striker block and spring kit for a DIY trigger job which is several steps beyond what the M&P Pro offer...they even include a "duty" spring for folks who want a bit heavier pull (the kit lowers it to 4lbs, the spring brings it to 5.5lbs)...a competition spring is also coming

    they have an extractor for folks who are going to put their 9mm M&P to heavy use and are working on a HD trigger bar also.

    if you want to optimize your M&P, Apex Tactical products are the way to go

    Speaking about M&Ps and the Apex sear, firing pin block and springs check out this review I wrote on all the beforementioned products.

    I see what You're saying Hangingrock. The only reason I said that was I only had the malfunction once. I was also going to have my gunshop look at it and test fire it before I traded it in. Perhaps I should have it looked at by S&W first.

    Best wishes,
    Evan

    I would definitely give S&W a chance to fix the extraction problem.

    Was that a hollowpoint by any chance? The short OAL on some JHPs can make it easier to "drag" a second round forward in the mag and cause stovepipes/double feeds if it's not extracting cleanly. You might even be able to duplicate the problem by hand manually. Was a full mag or was it one of the last rounds---less spring tension? It could even be mag related.

    I would expect you to be able to contact S&W by phone or email, explain the problem and they should send you a shipping lable to return it for checkout and repair. Be sure to give them all the details--ammunition, number of rounds in the mag when it jammed, etc.

    P.S. If my CZ didn't feed a round with a firm mag insert, I'd pay extra to get one that did. The top round in the mag lifts the slide just a skohh and allows it to release from the slide lock.

    i disagree, there are alot of big name folks in the industry that are using them, and they have had great results or they wouldn't continue using them. These guys put alot of rounds down range, and run thier guns hard. when some of the biggest names in the training community are using them, that says alot, or it should.

    I think the OP is jumping the gun considering he's had one feeding malfunction. If this is a continuing problem the gun needs to go back to Smith & Wesson. It may be the case that the gun will fire the next 1000 rounds without a problem.

    As far as the slide releasing on mag insertion, are you slamming the mag in full force? Many gun designs will do this.

    The slide closing on mag insertion:
    my USP does that when I slam the magazine in,
    when I gently place it, the slide stays open.
    I like it like that, just have to make shure the barrel is in a safe direction, when inserting a new mag (as always!!!)

    Personally, prior to the M&P, I modified guns on purpose to do that. With the M&P, I didn't have to which is a plus. Also, as has been said before, if the extraction problem does not go away, send it to S&W and they will take care of you. I almost wish my S&W guns would have a problem since their customer service is IMO the best in the industry.

    Do you realize how ridiculous that sounds ?
    Be careful what you almost wish for.

    If the double feed only happened one time I would shoot it like crazy and see if it happens again. It could be a couple of things, ammo or operator error, anyway I wouldn't give up on it quite yet. As already mentioned a few other times, the slide chambering a round is a good thing for speed on combat reloads. I love that about my M&P.

    I beg to differ, I have waited a long time for a semi-auto that does not feel like I am holding a 2x4. S&W has done wonders with the 45 ergonomics.
