looking into buying the apex trigger spring kit but im curious to hear peoples reviews about it. is it worth it? any problems that were encountered? does it provide a more smooth and more crisp trigger pull than stock?

also i read that there is a magazine extension for the sd9 mags? where can i find it?

I installed the Apex springs and the AEK aluminum trigger in my SD9VE and it did lighten the trigger pull by about 3 pounds. (I have not checked the actual weight I'm just going by the feel of it) It is very smooth.

I don't believe that the extensions are for sale yet but were released to a few people to test.

also, would polishing internals void the warranty?

I have not done that just in case. I was kinda curious about that myself.

There is a extension for the mags but its a prototype, not in production yet but a few members here were given testing peices.

Polishing gives a smoother pull and a better stage for precise shots and it reduces future wear. Polishing tge feed ramp allows better feeding of rounds and less future jamming, i polished my whole barrel to reduce any friction with blowback and lockup.

People have said polishing will void warrenTy but it seems S&W CS differs per case and results are different also. If you want a definite answer i would call S&W to hear it for yourself and decide wether to proceed or not, i did and Im very happy.

I installed the apex spring kit in my sd40ve. It went from an 8lb pull down to a 6 lb pull. It is much better than factory. Its lighter, maybe a little smoother, its still just as long as it was, I wouldn't call it "crisp" at all. I did the light polishing as described in the video. I dont see how that little bit of polishing could possibly void a warranty. If you haven't watched the install video on the Apex website, you need to do so. I dont think you will be disappointed with the spring kit.

I have the spring kit and the Polymer-AET Trigger installed in my SD9VE. I also polished the feed ramp and the trigger bar where it connects with the sear and the striker block. The result is a smooth trigger pull of slightly above 6 lbs with no over travel at all. The +3 mag extensions are in beta test phase . As soon as they are up for sale I'm sure you will find them on the Apex website. I think that polishing of the internals only void your warranty if you disassemble the gun further than you would do for normal cleaning and maintenance. But to be sure check with S&W CS. If you are going to polish keep in mind that you don't want to remove material just friction.

Wow your guy's pulls still up there with everything. Mine has everything installed except i have a M&P AEK trigger in mine (had it in before Apex released the AET Trigger) and GP SS 20lbs guide rod. The apex spring kit and polished every metal part on the gun. I also use dry graphite lube on my striker, gets cleaned and reapplied every use. My pull sits at 4lbs 12ounces and i can feel exactly where to stage the trigger before it breaks, and it does like a glass rod.

Ive asked this question before and have received no real answer. Has anyone tried the galloway precision search spring with the apex kit? I believe it may reduce the pull further but didnt know if it cuased light strikes.

search is your friend.

I rec'd the Apex polymer SD AET and replaced the stock trigger, it's the only modification whatsoever to my SD9-VE to the workings of the gun. I'm liking it so far...dry fire only...for real hopefully this weekend. I like the differences even if I can't articulate what they are yet. It works even keeping the stock/no springjob pull on it. Kind of...fine touch but with less fanfare as the whole pull mechanic happens with more precision but in less pull distance at once. The "roll" putting english-on-my-pull deal I developed along with using very close to the middle-tip to articulate the trigger....none of that is needed anymore. Although I did get rather good with controlling the pull, I guess if I prefer it the hard way I can replace it, but that's not gonna happen. This trigger feels just about as good as my friend's H&K USP Tactical .40 stock trigger. Whatever that means, but that is a really damn nice gun (and trigger).

I have just purchased the Apex spring kit and the Polymer trigger, for my SD9VE, Apex post a video on their site to install the spring kit. However they do not give a video or instructions on how to install the polymer trigger, do any of you have exprience with the installation of the polymer trigger, via instruction or mayber pictures that would help.

I installed the spring kit first and felt some improvement in the amount of pull but still was not satified with the trigger operation. I ordered the apex trigger and installed it today. The spring installation was a drop in operation following the apex video. The trigger installation required some modification. The rear of the trigger required some extensive filing to get the pistol to fire. After completing the filing, I am very satisfied and highly recommend installing the spring kit and trigger replacement.

Just thought that if anyone who is installing the apex polymer trigger, all there is to it, is to punch out the pin that secures the factory trigger to the sear, and the apex goes right on with no, problem. Also, you might like to know my SD9VE is brand, new I have had it maybe 2 mos. the Apex trigger dropped right in without any alterations.

I have a sw9f and have both the trigger and spring kit installed in it for awhile now. It made a world of difference to mine. The pull went from over 8lb (10lb is a guess because my trigger scale goes to 8lbs and I had to pull "alot" more to have the trigger release) and was gritty. Now it is smooth and breaks at 5.2lbs. The trigger reduced the takeup by at least 20% and there is no noticeable over travel now. Here is a pic.

just installed my new polymer trigger but the only thing I notice is I file to much off. it fires with no problem but there a little bit of over travel. so my question is should I get another one and be more careful about file or the over travel won't make that much differents?

I currently have the Galloway Spring kit with the updated sear spring. I LOVE it!!! I kept the original striker spring. I'm not sure what the pull weight is, but it's very smooth. I also polished up all the contact points as well.

First time out, it actually caught me off guard on how sensitive it was. But, after a few rounds I got used to it and its comparable to a Glock 19, but cleaner.
