Today we have a treat for you GU readers. We are taking an in-depth look and review of the Smith & Wesson M&P Shield Plus 9mm sub compact pistol. The Shield is one of many CCW focused handguns with features and design to benefit today’s concealed carrier.

  • Action Striker fired
  • Capacity 8
  • Optics Ready No
  • Sights Fiber optic

S&W M&P 9 Shield Plus Background 

The M&P series of pistol has a long history of service, and with the Shield model Smith & Wesson brought that reputation to a micro-compact pistol. The Shield was designed to maximize features in a very small and portable handgun. 

The Shield incorporates the handsome cuts and rugged features familiar to all pistols in the M&P line. It compresses these prominent features into a narrow and small framed polymer-framed pistol to give its owners an edge when they need it most. 

M&P pistols have been around for a long time, but the Shield is a much newer development. The first M&P pistol goes back as far as WW2, a revolver chambered in the .38 Special. The lines focus on military and police service seem more like a tradition now than anything. Selling weapons to law enforcement and not the public is scandalous at best. Let’s hope firearm manufacturers don’t need to relearn that lesson. 

The Shield has an incredibly narrow design, which makes it a particularly good choice for a carry pistol. The engineers at S&W worked some impressive magic, fitting all the M&P goodness into this slim and sexy little pistol.

S&W M&P 9 Shield Plus – Review

SW MP9 Shield Plus Hero

To test the Shield, I grabbed several boxes of ammunition and headed into the mountains to give it a good thrashing. Both my son and I spent several hours shooting, loading, and shooting some more with the little Shield.


The small size of this pistol is impressive. When you hold it in your hand, it is surprisingly narrow.

It might almost even be too narrow if you are a person with really large hands. With a full magazine, the pistol still felt quite lightweight. 

SW MP9 Shield Plus Appendix

With all that in mind, I anticipated a pretty good snap when the little Shield went off. But to my surprise, it was much easier to control than I expected. This surely had something to do with the ported barrel. The muzzle blast created a visual V of flame and kept the pistol from rocking excessively in the hand. 


The trigger is just the right amount of length, in my opinion, for a CCW pistol. It breaks nicely and predictably. This made shooting the Shield very pleasant and also allowed me to shoot it quite accurately. 

The narrow grip that I thought might be too thin was actually very comfortable. The very low profile safety seemed to be almost too low profile, but disengaging the safety was actually just fine. It took a little more deliberate effort to engage the safety, but using my thumb to move it to the fire position was flawless. 

The magazine release also took a little more deliberate effort, which is probably a good thing for a CCW. The only thing I disliked about the magazine was the spacer at the bottom of the floor plate. It had a little play that could cause some fumbling when seating the mag. 


SW MP9 Shield Plus Sights

The fiber optic sights were fantastic, the red rear sights contrast beautifully with the green front sight. The sights popped even in the lowlight of a cloudy evening. And made for one hit after another. 

Hitting targets within 20-30 yards was very doable. The short stature of the Shield did not seem to inhibit my ability to shoot it well. This is a big plus, in my opinion.

Drawing the pistol from a holster was clean and smooth. The edges of the pistol have just the right amount of softening to avoid snagging on clothing. The grip angle kept the pistol on target everytime I presented it on target.


While I prefer more than 10-rounds for my CCW pistol, the Shield really seems to be a valid contender in my estimation. It actually surprised me to see the MSRP of $499 after playing with this pistol for a day. It really did impress me more than I had expected. 


Shooting the M&P Shield was a surprisingly pleasant experience, not that I expected it to go poorly. I just liked it much more than I anticipated. The compact size of the Shield makes it an excellent choice for concealing. And with the reliable function and heritage of the M&P line, it will stand up to daily carry. 

The bright sights and grip angle make it easy to get on target quickly. The only drawback I could come up with really is that it holds fewer rounds than other options. There are several great models in the M&P Shield Plus line. Surely you can find one that fits your needs best.

Report Card


The Shield is very comfortable to shoot, and easy to control despite its small stature.


We experienced no malfunctions during testing. It runs like a machine.


The grip is a little narrow for my taste, but it didn’t seem to affect my shooting.


For a pistol this small, it shot very well. Keeping patterns under three inches at ten yards.


For the price of the Shield, you get excellent features and performance.

  1. I have the Smith&Wesson Shield Plus 9mm and the Springfield Hellcat as carry guns and it’s about a dead heat on them. Both are great carry guns. The new flat trigger on the S&W is as good as factory triggers get. Fun to shoot. Both guns are easy to hide even with Red/Green Dots on them.
