New S&W M&P 9 Woes

I picked up a S&W M&P 9 Range Kit recently. At first glance, it's great value. You certainly can't go wrong with what you get in this package. I knew from the start that these guns lack the tactile trigger reset that other guns have. I was okay with this because I had already ordered the Apex RAM and the Apex DCAEK to take care of that. Then came range time.

I put a couple of boxes of Wolf reloads down the pipe and it ran flawlessly. It takes a bit of getting used to, having been shooting a heavy CZ for a while, but I liked it so far. However, I couldn't for the life of me get the magazines to drop freely. I though maybe it was because it's brand new and needs a bit of wear, but then somebody else at the range mentioned he was having the same problem with his new M&P.

After a bit of investigating, we've come to determine that the problem might be with the mag followers. It's hard to tell from this terrible cell phone picture, but you might be able to see that there is a very slight difference on the right side edge. The follower on the left is from a new kit. The right edge slightly sloped. The follower on the right is from an older model. The right edge is a nearly perfect 90 degrees.

What's happening is the slide lock/release lever is getting caught on that edge, essentially holding the mag in place. This only happens when at slide lock with an empty magazine. With rounds in the mag, it drops freely because the lever doesn't get caught on the plastic - the round is there to prevent it. So, we've ordered some replacement followers. We're still waiting for them, but I hope we get a good batch of them.

Now, back to the Apex kits. I open the box and immediately start taking apart the gun to get the kits installed. Big question mark on my face. The RAM doesn't fit. I double check pictures and videos for a little while to make sure I'm not going crazy. Then I go to the Apex website and notice a warning stating the RAM kit might not fit some newer models, including the VTAC edition and the 45 calibre model. I should have known not to buy the kit from Brownells. Their site didn't specify this. I suppose it's partly my fault for not having done mre research, but why would I have any reason to doubt them?

So, as it happens, the new M&P 9 comes from the factory not only with newer Sear Housing Block but also with the frame used for the 45 calibre model. Here's a comparison of pictures I grabbed from the web. I can snap pictures of mine when I get home. The SHB on the left is the newer/VTAC model which does not accept the RAM. The one on the right is the old model (this one happens to have the additional safety on it, but can be removed). The frame on the left is the newer/45 with the square plug. The one on the right doesn't have the cut-outs.

Unfortunately, Apex doesn't have a RAM that fits at this time. They were supposed to have one released for the VTAC early this year, but I'm told it wasn't ready and they don't have an ETA. The DCAEK however will still fit, which should still improve the trigger. On the bright side, the VTAC SHB does provide better reset feedback than the old one.

Other than that, I've installed a HiViz front sight on it and will now take it to the range to zero it. I'm crossing my fingers. I was hoping to fall in love with this gun, but so far I'm not impressed. We'll see...

I had exactly the same problem with two out of five new M&P9 magazine followers. I ordered a couple of replacements from Brownells, and they work perfectly now. The Canadian S&W warranty center offered to replace them if I sent them in, but I needed functional mags for some comps and couldn't do without them temporarily.

I have a newer M&P9 with the new sear housing block, and I don't think the reset is a problem at all. On mine, it feels about the same as a stock Glock. But it's personal preference, of course.
 
I can see you not being happy with the mags but I don't understand why you're unhappy with the pistol because aftermarket parts weren't designed to fit it.
 
It's not simply because of the aftermarket parts not fitting. I don't blame either company for compatibility issues. What I'm unhappy about is the hassle I'm going through with a brand new firearm and magazines that won't release freely. This shows a lack of quality control.
 
Tell you what - I just got a swack of new followers from Brownells, PM me and I'll send you 2 or 3. As far as the RAM goes, the reset is more noticeable once you get rid of the 'false reset'. The best way to do that is with the DCAEK. Then if you still want a more tactile reset, you can gently tweak the trigger bar inwards on the pistol, which increases the felt reset. The sear block on the left is the one that works with/without the thumb safety, I'm pretty sure it isn't the same as the 45 - the 45 is physically bigger and the ejector on the 45 is slightly different (or at least it was). It's been a while since I had an M&P 45.

I can absolutely understand being upset with the mags.

Agreed. The retailer should give you new mags without question, and they can deal with the warranty delay.
 
So a fella here (thanks again enefgee) sent me a few new mag followers he had laying around. I immediately popped one into one of the questionable magazines and BAM! I tried as hard as I could to get it to jam but it wouldn't. The mag now drops freely on slide lock. Now I'm happy.

Good ol' CGN collaboration.
 
The picture you picked off the net is a Compac model. The .45 frame is not the same as the 9/40 frame. You have the 9/40 frame. I bought the RAM kit and found it made so little difference, had I known I would not have bothered with it. Some do like it so there you go. You won't be missing mmuch if you never get it installed IMHO. The new sear block is an improvement over the original...be happy. S&W is making thousands of these guns so you should not be to surprised if you have a minor problem. Hell I spent $40K on a car and had it back to the dealers within a month for service. You buy a $700 gun that wholesales for 1/3 of that and are dealing with a very small issue.

I have the frame with the square plugs. Show me on the 9 and 40 where the plugs are and I'll believe you.

The dollar figure doesn't make it any more acceptable. I've had issues with brand new vehicles too. It doesn't make it a better or worse situation. Small issue or not, a customer shouldn't have to deal with something like this right out of the box.
 
Show me your gun with a .45acp mag inserted in it and I'll believe you. Square plugs and round plugs don't have much to do with the size of the frame.
 
So I have this same problem. I just assumed it was a nature of the gun. When I set my hand on the mag release I don't feel it move when the inserting the mag and feel the first sticky point. Would this still be the follower catching on something else? oR is the mag well maybe moulded a bit too snug? If when ejecting I give a slight flick down the mag will drop free.
 
Ebbnflo - check to make sure the mag release wire (which acts as the spring) is properly seated in the mag release - if it isn't it can cause these issues, and it can be a bit of a bugger to get into the right position.

Depends. Remove your slide and insert a mag. Does the slide stop sit on top of the mag follower, or graze the side of it? Here's what my "problem" followers looked like when they were inserted in the gun:

As you can see, the piece of the slide stop that is supposed to sit on the top of the shelf on the follower is catching on the side, preventing the mags from dropping free. Replacement followers eliminated the problem.

EDIT: oops, you don't need to remove the slide to check.

Send one over. lol

All I'm saying is I have the frame with the square plugs and the new SHB. I have new followers now and I've come to terms with the fact that the reset isn't what I'm used to. I'm okay with that.
 
Are you referring to the upper right section of the mag? Where the follower is just down slightly?

So now after playing around with them for a bit. I have 2 that drop freely pretty much every time. 2 that do not. they get stuck on the way out...

That is very strange, perhaps something isn't working? My M&P Pro (9mm) had almost zero tactile feel when the trigger was reset and once I installed the RAM it now produces a nice sound and very noticeable reset. At least this was my experience with the RAM, before and after.

Ya you won't likely notice it when you are shooting. The only time I think is is an issue in my head is when I am watching TV and slowly releasing the trigger to hear the reset. When the timer goes off or when I am doing double taps I have no idea as I just seem to run the gun.
