Make M&P9 frame heavier. Is it possible?

jurek · Aug 6, 2021

Hi guys,

Does anyone tried or found the way to make M&P9 frame heavier?

I don't want to use heavy guide rod or recoil assembly because it actually change slide's weight, not the frame's.
I know that SIG P320 uses tungsten rods in the grip, but M&P doesn't have room for this.

Any thoughts or ideas?

Not on the frame but it won't be much but aluminum +5/6 mag pads. Maybe you could diddle filling them with a bit of weight?

Attach something to the pic rail?

I like the idea. This is my carry firearm and I'd like to avoid extra grip length... but perhaps I'll be able to fit tungsten plate in existing base plate.

Thx for the tip !

May I ask the goal of adding frame weight to your carry M&P?

Comfort.
I found myself better operating non polymer handguns (like SIG229, P320AGX, 1911s, 2011s) . Their weight is balanced better.
But I love my M&P9 and would like to make it better fit for me than replacing.

Ah yes, weighted base plates and the "Seattle Slug", designed to add weight to the "plastic fantastics." An old idea that works and is illegal in most competition. Moves the balance rearward and down, and gets unwanted attention from tech inspectors at matches.
One legal way of doing it in IDPA is using heavier bullets, but of course the balance changes with each shot.

I’m not sure what amount of weight you feel you need, or where you would like it.

Assuming you want some balance, maybe even more toward the front to reduce muzzle flip, you can fill in the pic rail notches with lead plugs then use a two-part polymer to seal them in place. Sand, then Cerakote. You might gain 3-4 ounces.

Similarly, if you remove your back strap and check both the frame and the back strap, you will find more space for weight there. 3-4 oz?

Extended mags with more ammo and weighted base plates. Another 3-4 oz?

A total of 9 oz? Is the juice worth the squeeze?

OR You could spend $120 on this--> SJC Full Size M&P Frame Weight - S&J Customs
6.3ozs
No way I'd spend $120 on a weight..
Picture shows a Glock BTW

Hi guys.
Thank you for all suggestions.

Problem has been solved... actually sold.

I switched to 2011 and started carrying what really sits great in my hand.
