Hello, new to this forum. I just purchased a used Smith & Wesson and I am trying to find out anything I can about the handgun. I have asked the manufacturer what model I have and what the serial number shows but haven't heard anything. SO, I am hoping
someone in the forum can help me. The only information on the slide is M&P40 ( no, not the German machine gun) so I guess that is the model? The serial number is MPW2149 and I'm hoping someone can tell me how to read the serial number or anything about my newly acquired handgun. I was told it is a used Police gun. If I did it right there should be a picture of my gun.

Thanks in advance
Steve

Yes, the model is M&P40. I've got one just like it, and it's a great gun. If it's a police trade in, it probably has the magazine disconnect apparatus. I removed mine.

Overall, it's one of the softest shooting 40s around and a great value (depending on the price you paid). I don't like it as well as my HK VP40, but that's just a personal preference. If you find that you like it, you can add a few things such as an APEX trigger, a 9mm conversion barrel, and some new night sights. I did all of these things and it made a good pistol even better.

I still carry a early M&P 40 4.25" barrel full size like yours but with thumb safety's . With out the box for your handgun the SKU: number is unknown but not really worth worrying about . S&W should be able to date yours by the serial number.

I do see yours has had a sight change and shows zero holster wear ! Mine does have a apex fss trigger kit but with apex curved trigger . Your mags may show wear and if you can get a good average on the trigger pull weight you may find your pistol is closer to old new than well used .
 
Due to the word STAINLESS rollmarked onto the slide, the beavertail, the finish, the visible provision in the frame for a thumb safety, and the trigger, your pistol appears to be an early generation M&P .40 exactly like mine, except unlike mine, you likely have a magazine safety since it's a police trade in.

Yep, early production M&P40 like Oldsalt says. Also note yours has the provisions for the internal lock (but not installed in your particular unit) rather than the manual safety. S&W announced the option for a manual safety around 2009.
 
The frames and sear housings are different between the models like the OP shows and the ones with safeties (or the ones with the plugs in the side of the frame when there are no safeties.

I like the 1.0 frames better than the 2.0 models. I like the trigger/internals on the 2.0 models better than the 1.0 models.

Last I looked (a day ago) Aim Surplus had used LE .40 magazines (15 round capacity) for $13 each. I got a few more. If you want more, don't wait, they don't last long.
 
Thank you to all who replied to my quest to find out about my newly acquired used MP40. Smith and Wesson did get back to me and informed me my pistol was manufactured in September of 2007.

Yup, I should have said "internal lock" but instead incorrectly typed "thumb safety".

Even the directional arrow for a key is present on the frame although there's no lock.

Thank you for the correction.

IIRC, later iterations had a square cut in the frame for a thumb safety whether or not a thumb safety was installed.

You are correct. The later frames had the notches fab'ed in and small block to fill them in on SKUs without the manual safety. Made it easy to switch over if desired. The issue going from safety to no safety was finding the small blocks.
 
A 1911 Commander-size in 40 S&W has enough "meat" in it to make recoil -0- (almost);)

A real pleasure to shoot, especially after learning the basics on a .22.
