Hi Joaquina, and welcome to the forum. Yes, the model 11833 Smith & Wesson Performance Center Ported M&P 9 M2.0 & Slide CORE 9mm Pistol comes with the required 1/8 inch sear spring and plunger set up. Cheers, stay safe and enjoy!

Hi Joaquina , yes this will work with model 11833.
For use in all M&P M2.0 polymer frame pistols in 9mm, .40S&W, and .45ACP, including the Full Size, Standard, Compact, and Subcompact.
EXCEPT for the Shield and Shield M2.0.
Also for use in the original M&P 45.
NOTE - This kit REQUIRES the use of the larger 1/8 inch sear spring and plunger set up. If your M&P has a 1/16th inch diameter sear plunger and spring, we strongly advise you upgrade to a new style sear housing block before installing this product. All function and reliability testing was done with a 1/8 inch sear plunger and spring, therefore we cannot guarantee proper function without the appropriate size sear plunger and spring. Modern sear housing blocks can be found on Brownells.com and other online firearms product retailers.
Stay safe & have a great day!
