Yet another trigger and slide question.

I have a 9mm Pro Series. The trigger is horrible. Nasty. Crappola. Junk.

I thought/hoped it might settle in after a few hundred rounds but it has not. You all know this and have experienced it I'm certain, but just to be sure......

1. Pulling the trigger back it feels stagey.....there are perhaps 5 distinct bumps or stops if you pull it slow so you can feel it. If you pull it normally there are 2 distinct bumps. It feels like a 3-stage trigger LOL!!

2. There is a long take up, way too much.

3. The hinged trigger feels spongey. I don't like the hinged trigger.

4. The break is mushy.

5. The trigger break is too heavy.... 6.25lbs.

6. The reset sucks.

Basically the entire movement of the trigger feels like rubbing two pieces of slightly bumpy plastic together, the hammer feels like it is propelled by a rubber band and it feels like a 3-stage trigger with a non-positive reset.

So my main trigger question is......what Apex kit and/or additional parts do I have to get to make my 9mm Pro Series feel more like a 1911 trigger?


I feel like I don't want a hinged trigger and I feel like an aluminum trigger would be best. I also want to reduce the pull weight?

Since the gun has no safety is moving away from a hinged trigger a bad idea?

As far as the slide.

1. The slide to rail fit is not as tight as my 1911. I can feel play there side-to-side. Does anyone know how much is considered in spec?

2. The slide/recoil spring feels quite stout and is also "scratchy" when racking the slide. You can feel it rubbing on the guide rod.
Is there a better spring people are using here, one that is overall way better than stock?

Lastly, if there is a general spring kit or combination of springs that people here like, I'd love to get than info.

Basically, I want to get my 9mm Pro Series gun to actually feel like Pro anything. I feel like I paid a little extra to get a basic firearm. S&W says the Pro Series fills some sort of gap between a stock pistol and a custom shop gun....something along those lines. I don't feel anything special about it.

That said......should I send it back and have them tweak it?

I did some research and Youtubing.....and found some interesting stuff. One of the videos talked about the disconnector, or striker blocker, as being a culprit in the grittiness department. Striker blocker the right word?

So I stripped the pistol and polished the disconnector/striker blocker....polished the area of the trigger bar that rides over it...and polished the bore the blocker moves in. While I had it apart I also polished the feed ramp.

Lo and behold, it actually improved things a little as far as feel and amazingly....the pull weight came down from 6.25lbs to just over 5.5lbs.

Damned if the trigger does not feel acceptable now. It is still not what I want though. I'm going to order the Apex kit. Their barrels look interesting also.

APEX the whole gun... best money you`ll ever spend on your M&P Pro.

The apex trigger kit will make a huge difference. There are multiple options on their site, and I would suggest research there to find exactly what you are looking for. They have kits with aluminum solid triggers, yet still have the trigger safety, via a small lever, that works like a Springfiield or a Glock. They have kits from about 3.5lbs to 5.5lbs, and most kits have different springs, so 2 options in 1 kit.

I have the full PC ported full size 9l version, and the trigger was very nice out of the box, except for the almost non existent reset. I started with the Apex Ram kit and ended up doing the whole thing with a flat faced trigger, and used springs that got me to just under 4lbs. My PC Shield, I only changed the trigger itself to the 1 piece aluminum.

Here is the site:

The striker block is where the grittiness comes from.

I don't know how light you want your trigger pull.

My M&P9 I put the CAEK in averages two pounds seven ounces.

I just replace the sear and striker block in my carry M&P's, and wind up with a trigger pull between 3 1/4 - 3 1/2 pounds.

The Apex Forward Set Sear Kit will get you 1911's feel. I have them in pretty much every one of my M&P's.

Initially, it sounds like you made a mistake going from a single/ double action 1911 to a striker fired pistol, however, I had similar issues with my shield. I put just a polished sear and later aluminum flat faced trigger in it. It came with (for some reason, an 8 pound trigger that felt like I was pressing through a sheet of sandpaper, after the two mods, I reduced trigger effort to a smooth 4 pounds. nice break with no creep and a decent reset fast forward to now. I have about 1500 rounds, through the completed job. Lately, it has felt too light, I measured it with my lyman and it is an average of 2# 8 oz. still smooth but too light. (yes I know weight is only one of the criteria, but it just felt too light for cary)so last weekend I removed the apex sear and replaced it with the original sear. I am back up to 4# 6oz and with the aluminum trigger it is still smooth with acceptable components. Now, if I get another new shield at some point in time, I will put in a trigger first (and keep it) and the sear too, until the pistol is broken in and then pull the sear. back out. So, give yours a chance, either with time or a bunch of ammo is will be everything you have dreamt of . good luck and good shooting.

I think you meant single action only for the 1911 oldfart. The only thing double about it is double the fun!

Seriously though, I didn't expect the M&P to be remotely close to the 1911......I did however expect it to be a major cut above the Shield, which I already owned.

Any of the complete Apex kits will get the trigger as good as it can get. If you carry the gun get the carry kit. If you shoot competitively get their competition kit.

No. The aluminum trigger has the center trigger safety and is as safe as any other type of striker fired trigger system safety.

Which brand 1911 do you have? If its upper end competition style the frame to slide fit will be tight. Combat level guns are looser for a reason.

Stainless Steel Guide Rods and Galloway Precision to name two manufacturers of aftermarket guide rod assemblies. I have Galloway.

Just checked Galloway and could not find recoil springs for the Shield, but did find it at Stainless Steel Guide Rods.

My slide is very stiff to rack even after over 1,500 rounds. Will this recoil spring make it lighter?

TIA.

I believe so. This spring kit is not recommended for +P loads so it should be lighter.

1) Hard to say, we have no idea what the spring is rated at.
2) You`ll likely feel more recoil with the single recoil spring too.

Thanks guys. Guess the only way to find out is to get one and test it. Just read the two good reviews.

Hopefully yours is the standard shield...
They say their guide rod assembly wont work in the performance center shields.
I dont see why they wouldnt work in the PC shield`s, same assembly in both guns.
