Smooth pull
Since i recieved this gun as a house warming gift from my buddy when i moved to florida, i did research on this police gun. I read other reviews and decided it could use a upgrade. This gun has been discontinued and some parts are unavailable. The trigger/ sear was a tremendous difference. It was easy to put in and range target accuracy improved noticebly ..
Easy Upgrade of original M&P Sear issues
This Sear assembly has the newer, larger Sear Plunger and spring that helps with the original's Sear bounce and was upgraded after, about 2010 models forward. If you're an owner of an earlier, first series run of M&P (9, 40, or .357Sig) models and have not made the upgrade, this is the one for your pistol. If you're planning on doing any kind of trigger upgrade, nearly every one will require the larger Sear plunger that comes in this assembly. I've read some people saying it required fitting, this was s direct drop in part for my M&P40, that is the same exact pistol as the M&P9 and .357Sig as far as the lower frame is concerned.
Updated part
This sear block DOES include the newer updated 1/8" sear spring. If you have the older model M&P this will update it to the newer stronger sear spring required for Apex trigger components. I'm not sure why the other reviewer said his didn't come with the larger spring because mine did. This model also comes with magazine sear disconnect installed but can be easily removed by transferring over your old parts to the new block.

The internal locking mechanism can also be removed with a punch and a couple taps with a hammer.
Must have item
Must have item for MP owners, you don't know when you need it. The IS was very easy to remove.
Exactly what I wanted.
I wanted to upgrade my carry guns sear housing block to the one with the larger sear spring and plunger. I was very pleased to see the large spring and plunger underneath the sear.
This is what you need.
I needed an updated M&P sear block with the larger factory plunger and spring, this is what APEX recommends when installing their FSS trigger.
Works with apex, but......
This will work if you are needing the larger sear spring for apex trigger jobs. As some others have said, you can remove the magazine safety and use your older parts. The catch with this is the frame lock. You can remove by installing sear block in vise and use 1/8 punch to back it out. You can then reuse the RAM from your other sear block assembly or use a new apex one as i did. I did have a challenge installing it with the frame safety plug on the frame. Some grease and prying finally got me there.
Has 1/8" plunger (and frame lock)
This does have the new 1/8" plunger which is what I needed for the Apex trigger. The block also added a magazine safety and frame lock which were not on my pistol originally. I point that out because mine can locked and I didn't realize it before install. I though I installed some wrong until it can to me that it had a frame lock and was engaged. (I noticed the magazine safety before I installed). Luckily I had a Smith and Wesson handcuff key near by and used it to disengaged the frame lock. Worked perfectly once that was done.
OEM replacement part
The part seems to be of high quality and was a direct replacement for my older style block. However, you should be aware that this block includes a magazine disconnect and a frame locking mechanism. The magazine disconnect is easy to remove, and using parts from your old block to put it together. However I'm not sure if you can remove the internal locking mechanism.
