M&P 2.0 Differences I See

Picked up a MP9 2.0 Full Size the other day.

Not yet a complete list of changes I observed compared to MP9 Version 1.0:

Frame:
1. Rear “beaver tail” has been shortened by 0.35”, the OAL thus shortened to comply with U.S. Army Modular Handgun Standards (MHS).
2. Forward locking block slide rails length doubled; 1.06” from 0.47”
3. Forward longitudinal ribs molded in dust cover presumably to add rigidity.
4. Trigger bar-sear mechanical engagement geometry.
5. Magazine catch release profile is different.
6. Asymmetric Slide Stop Lever profiles; left side 0.25” v. right side 0.21”.
7. Locking block and sear housing secured with 1/8” solid pins, no longer roll pins.
8. Trigger over-travel stop molded into trigger guard.
9. Serial No. placement moved forward, presumably etched into forward extended steel chassis.
10. Matrix QR (Quick Response) bar code adjacent to serial number; contains all the information about the specific gun build.
11. Underside barrel support surfaces increased width, 0.145” from 0.125”
12. Take-Down Lever now retained by its positioning between the outside of the forward locking block and inside of frame wall; no more small spring to lose and the Lever can only be removed upon the locking block being liberated from the frame.
13. No Slide Lever Spring integral to the Slide Stop Lever.
14. Slide Stop Lever spring-loaded detent integral to left side of frame.
15. Ejector profile thicker in its forward projection.
16. M&P logo used instead of Military-Police logo on lower outer surface of grip.
17. 4 modular grip choices, “medium-large” added.
18. Aggressive texturing of grip.
19. Reduction in trigger pull weight:
20. Take Down Tool has lanyard retention point; the original Spec-Ops model was the first to feature it.
21. The profile of the rear trigger guard-frame has been thinned, much in the way most users have modified it to avoid wearing a hole in your middle finger with high round usage.

Slide:
1. Red striker channel liner.
2. Forward cocking serrations.
3. “M2.0” designation on left side.
4. Slide Stop notch profiles.
5. Armornite instead of Melonite corrosion resistant finish.
6. Sides of the slide contoured differently.
7. Ejection port profile and dimensions are different (more open space) to improve ejection reliability.
8. Slide is ~0.1" narrower at forward edge of breech. Safariland is slightly modifying its holster dimensions to ensure a Level 1 security retention is maintained.
9. Chamber indicator aperture on slide side is smaller.
10. Extractor claw profile is different.

Barrel:
1. 1:10” twist barrel for the 9 mm.
2. Unlocking of the barrel has been retimed so that it occurs later in the firing cycle. This, along with tighter production tolerances,
and extended forward frame rails, enhances accuracy. The U.S. Army Modular Handgun Standards (MHS) specified a 4 inch Ransom Rest group at 50 yards.
3. Armornite finish.
4. Breech-barrel geometry profiles are different.

1. Rear “beaver tail” has been shortened by 0.35”, the OAL thus shortened; to comply with MHS specifications.


2. Forward locking block slide rails length doubled; 1.06” from 0.47”


1. Forward longitudinal ribs molded in dust cover presumably to add rigidity.


1. Trigger bar-sear mechanical engagement geometry.


1. Magazine catch profiles different.


1. Asymmetric Slide Stop Lever profiles; left side 0.25” v. right side 0.21”.


1. Locking block and sear housing secured with 1/8” solid pins, no longer roll pins.
2. Trigger over-travel stop molded into trigger guard.


1.Serial No. placement moved forward, presumably etched into the forward extended steel chassis.
2. Matrix QR (Quick Response) bar code adjacent to serial number; contains all the manufacturer-specific build information about your gun.


Underside barrel support surfaces increased width, 0.145” from 0.125”.


Take-Down Lever now retained by its positioning between the outside of the forward locking block and inside of frame wall; no more small spring to lose and the Lever can only be removed upon the locking block being liberated from the frame.



No Slide Lever Spring integral to the Slide Stop Lever.

Slide Stop Lever spring-loaded detent integral to left side of frame.


Ejector profile thicker in its forward projection.


M&P logo used instead of Military-Police logo on bottom of grip.


The profile of the rear trigger guard-frame has seemingly been thinned in combination with decreased angular magazine catch profile, much in the way most users have modified it to avoid wearing a hole in your middle finger with high round usage.



Slide:
1. Red striker channel liner.


1. Forward cocking serrations.
2. “M2.0” designation on left side.


Slide Stop notch profiles; also appreciated different slide side contouring profile.

Thumbs up

Thanks for the detailed comparison. I'm sure that links to this page will be showing up on gun forums everywhere.

Good job!

Thanks Mike, I've been waiting for your analogy of the two! Just like in your M&P Anatomy Series Manual's, your descriptions and pictures are awesome!

Thanks for the info!
Along with the thinning, it appears it hasn't been stippled.
That was the middle finger issue I had, so along with stipple removal came thinning of the guard.

Thanks for a great comparison!
Most online and magazine articles mention the grip stippling, trigger and added palm swell.
Your work gets to the meat.

Cheers

The big question is whether an apex kit is absolutely still necessary as soon as you buy one?

NutnFancy on YouTube feels that the M&P2.0 trigger is a huge improvement, and that Apex will probably lose business over it, He really likes the 2.0...

I saw that review today. He does seem to like it. Too bad getting one in California is to expensive for civilians.

That's awesome thanks for all the work.
I wonder if the new guide rails can fit in a 1.0
From what I can tell I'd think they would.
