M&Pc New frame vs. Old frame

I'm not sure whether to purchase an M&P 40c with the older IL plugged frame or a newer TS plugged frame? What are the pro's & con's of an Apex RAM upgrade in the older IL M&Pc compared to a newer TS M&Pc? Thanks!

I believe with the IL frame,you have to hammer out the lock to install the RAM.
If you do, get instructions on how to do the lock removal (can be tricky).

The RAM on mine went in just by filling the hole when the sear block was out of the frame. I have the newer frame type on my full size and I think they are both fine. For me if there is a difference on the trigger reset, it isn't that noticeable .

Not being funny, but since I'm not familiar with the frame differences:

Did you "fill" in an existing hole, or "file" a hole in the frame?

No hole to fill. The parts are all installed in a vacant hole of the sear block.

Curious;
Can someone explain differences between "old" frame and "new" frame?
My M&P's are circa 2007.
I understand old vrs. new sear block.

Also interested in learning more about new frame vs old frame. First I've heard of it.

Newer frames have thumb safety cut outs in the frame that are filled with the cutout pieces of the frame. The older frame does not have theses cutouts and instead have these round holes that re filled with round metal inserts. this is also to correspond to the newer sear block that will not accommodate the APEX RAM part. the newer frame should incorporate the newer slide release that has a small bump that pushes the trigger bar to make it center more on the sear.

I think the last 2 lines of your statement might not be correct.
The bump on the slide release of the newer models was put there
to make the reset of the trigger more "tactical". As far as i'm
concerned it doesn't do the job. I don't think S&W is worried
about the trigger bar being more centered under the sear. Just
my $.02 worth, not trying to offend.

New vs Old frame

No Worries, I did purchase the newer slide releases and I understand that the newer trigger bar is curved slightly to enhance the trigger reset. I have the older full size and compact M&P with the IL plug and will put the APEX trigger kit and extractor in to both.

I'm curious on this too. A picture comparing them would be great. Perhaps someone familiar with this could post? Anyone? Bueller?
