I'm looking to buy a thumb safety lever from someone who removed theirs and wants to sell it. I'm looking to install it on an mp9c.
Thank you

I have one from a 40c I removed. Does your frame have the cutouts on it?

Thanks for the reply. I do have the cutouts. I'm assuming the 40 is the same as the 9. Come up with a price and I'll definitely take it.
Thank you,
Ryan

If the sear block is the same it will fit. Op just make sure the sear block you have is the newer one that can accept the thumb safety lever detent and spring.



The one on the left is the old sear block. The on on the right is the new sear block with the detent and spring for the thumb safety. The middle one is the new sear block but does not have the detent and spring installed and is the one that should come with the newer m&ps with no thumb safety but have the cutouts on the frame.

Hope this helps.

I've been looking for a thumb safety lever for over 5 mounts now and still nothing. I'm also on the SSS e-mail list. If anyone else has a thumb safety or 2 they took off Please LMK. I need 2 for my 9 & 45 but I'll be happy to get one. Thanks D.
