I know it’s odd, but giving serious thought into buying a 5” optic ready slide for M&P compact that’s not optic ready.

You got me curious, so I put the 2.0 9mm 5" slide on the 4" 2.0 Compact. Fit fine. Nothing was binding. I don't see why it wouldn't work, and I really like the way it handled.

Long slide with a Compact frame should be a factory offering.

Yeah the 4-5” stuff is all compatible with the different frames. The 3.6” is the outlier. Could be some goofy stuff with the metal frames I’m not aware of too, but doubt it.

Would you be willing to snap a picture? Could only find one so far.

I believe that there is a significant gap between the frame and dust cover in that particular combination.
In the 4”/5” combo has just a little overlap that keeps it aligned. I don’t know if that gap would be a problem in reality though.

Frames all have 3 Picatinny slots. Also found this photo.

I would have snapped a pic, but that's the spittin' image of what I did. The two tone looks very nice.

Where are you looking at the optics-ready slide? I have some cash to play with and want to dick around with a dot.

Midway has them for a little cheaper ($275) than S&W sells them. They’re complete minus the barrel and recoil spring.

I put my 2.0 FDE 5" 9MM slide on a 2.0 FDE Compact frame for a short bit.  Functioned fine.  Felt funny with the shorter grip and 15 round mags.  I bought some of the spacers later to fill that gap between the frame and the 17 round magazine floor plate and that made it feel better but then I had a full size frame again.

I finally bought another full sized FDE stripped frame and built it up and then bought a 4" .40 S&W slide and put on the Compact frame.

Yeah, the 5" slide has an Apex Tactical threaded barrel in it (in attempt to get decent groups out of the pistol) and I put that comp. on it just to see how it compared to my ported PC 5" 9MM.

Sweet. That's not a bad price.

Man. I bought mags for my 2.0C about 6-8 years ago and had to buy full size mags because I couldn’t find compact mags. The FDE ones were especially vaporware.

Looks like nothing has changed. That’s absolutely crazy mags for these are still so hard to get. I think I’m actually going to abandon this idea because of it.
