I've got a RAM I can sell you if you want. I could not use it on my M&P .40, because of the design of the sear block. You may want to check yours 1st. I could not find anything local, so I got mine from Midway USA.
I don't have a thumb safety or a magazine disconnect. My sear block is the same as the VTAC model. I didn't know until I got it taken apart. I'd take $20 for it.
