Double Diamond 3.5 Pound Connector for G42/43/43X/48

SKU: 1104
Double Diamond 3.5lb Connector will let you reduce the trigger pull significantly.

This is a precision drop-in part that has been designed to improve accuracy and speed

Please Note: Fits Glock 42, 43, 43X, and 48. For all other Glock models, click here
The Glock 43 is one of the most popular guns in the Glock lineup. Along with the G42, it is a new statement for Glock; Single Stack, Lightweight, Low Profile, Easy to Conceal!

And, because of the polymer frame, both of these guns are a delight to shoot, very soft on the hands with minimal felt recoil when compared to other small concealed carry handguns. Plus, it's a GLOCK... enough said!

There's just one draw back, the trigger pull is extremely heavy on both of these guns measuring out between 7-7.5lbs. That's a very heavy trigger pull which adversely effects your accuracy and shooting speeds.

Our Double Diamond 3.5lb Connector will help you reduce the trigger pull significantly!

It's a precision drop-in part that has been designed to improve accuracy and speeds as it reduces the trigger pull to 3.5-4lbs. Each Double Diamond Connector is polished and coated in NP3 - a self lubricating finish that actually reduces friction of metal to metal parts.

Watch the video online for installation instructions. It's easy to do in 5 minutes or less!

Double Diamond 3.5lb Connectors are know worldwide as the best aftermarket connector for your Glock and are now available for ALL Glock models.

For all Glock models except the 42, 43, 43X, 48, click here

Well pleased!


Recently purchased & installed this Double Diamond 3.5 pound connector in my wife's new Glock 42. She was having trouble at the range with her ability to fire after about 2/3 of a box of ammo (She's a housewife, not a brickmason with massive grip & forearms). After the very first round downrange with the Double Diamond connector, the look on her face was priceless as she said, "I LOVE IT!". Installation was so easy, just followed Lenny's video - thanks Lenny for your great performance replacement parts and massive library of videos.

G43 connector


Ordered on Sunday, arrived on Wednesday.
The connector is every thing it is advertised to be.
Well made, nicely finished, easy to install.
No trigger gauge to measure the exact numbers, but the finger gauge
agrees it is about 3.5 to 4 pound range. (Not my first Glock, or first connector)
Good product, good price, good service.
Thanks guys.

3.5 disconnector Glock 43


Made stock trigger alot smoother. Thanks

Sweet Spot


I ordered the Double Diamond connector on Sunday and it arrived Wednesday. I installed it in about 15 minutes and let me tell you- this connector makes a HUGE difference in the trigger pull. Amazing difference for a great price. Way to go GlockStore!!

Makes trigger pull just a little more crisp


I'm about as novice to gunsmithing as one can be, and having Lenny's video to guide me every step of the way was extremely helpful...the end result was a crisper feeling trigger, although I wouldn't categorize the difference as earth-shattering.
I am sure the enhancement will translate well into the performance of my G43, and at the end of the day, I do recommend this product.

Impressed very impressed !


I don't generally do reviews but the Double Diamond connector works and give me the same feel / trigger press that I have on 2 other Glocks both are gen 3 with reduced power striker springs (everything else internal is stock) These Glocks have had thousands of rounds through them ! So you could say all of my parts , stock connectors included are worn in and are as good as it gets without modifications! This may come across as strange but all of my Glocks feel exactly the same ! This was definitely more than I was expecting ! Extremely pleased !

Double Diamond not 3.5 pounds


I recently installed the Double Diamond 3.5 pound connector for my G43. What a difference. Much better trigger pull, shorter pull and an easier pull. I put more rounds on target than ever before.

I had my gun smith at the range where I shoot measure the trigger pull. He consistently came up with 4-4.5 lbs. We tried it 10-12 times and the same results. I can live with that. It doesn't sound like much; but, it makes a huge difference.

Double Diamond Connector


This connector made a huge difference in the trigger on my new Glock 42! I have six other Glocks so when I bought this little gun I expected the trigger to be similar to my others. Wrong! It was much heavier and that combined with the very small frame size caused me to have a hard time keeping my shots centered and on target. The DD conector arrived today and I installed it immediately. The video that Lenny provides on the web site is an excellent tutorial. I watched it twice right after ordering the connector and then used it again while doing the installation, pausing the video after each step as I completed that step. The slightly greater angle of the DD connector compared the the original causes the trigger bar to rub lightly against the frame, but that doesn't seem to cause any problems. 50 rounds with the new connector installed and I was centered and on target except for a couple of pulled shots.

Great upgrade!


This upgrade really cleaned up the action on the trigger. Feels smoother and has a really nice reset. I gave 4 out of 5 because I didn’t quite get down to 3.5lb pull, ended up at about 3.8lb. Could be the calibration on my puller. Either way, still happy with the action.

Double Diamond 3.5 Connector


What a difference. Changed out the factory connector and man, what a difference. You can really tell the difference in this and the factory connector. Great product!!
However; I want to mention something else that I thing is so important and has been wonderful to have. And that is the videos that Lenny has done on changing out parts and such. I've changed several things on both my Glock 22 and Glock 43. Ive watched the videos each time and without watching them it would have been virtually impossible to do. They are VALUABLE ASSETS and Glockstore and Lenny ought to be very proud of them. They are just wonderful to have!! GREAT JOB LENNY!!

DD 3.5lb conmector G43


Swapped out the connectors and added the double diamond 3.5lb and noticed the difference in first pull! Helped with follow up shots and travel! Plan on getting 2 more for other glocks!

NP3, not crappy Glock plating


Same angle as the OEM, but the OEM like all of the Glock internals have plating issue. This one is NP3 and so therefore is superior.

G-43 3.5 Connector


9/29/18 Received the Double Diamond 3.5 Connector for Glock 43 plus a few other items. As for the Connector, I watched Lenny's instructional video, then less than 10 min install=TRIGGER IMPROVED! Great upgrade for a 43.👍👍👍🇺🇸

G-43 3.5 Connector


Installed DD Connector in my 43. I love it. $25 well spent.

Very good Product

I added the connector, and the tungsten rod, so I am commenting on both, since I shot after installing both. The weight added by the rod you can feel, reducing slightly the recoil and allowing you to reaquire the target more quickly. The trigger pull is crisper. I have been shooting Glock's since the late 1980's, and I have now shot my very best grouping ever.

Wow what a difference


I recently purchased a Glock 43. I was very disappointed in the terrible trigger. I purchased one of your double diamond 3.5 connectors. Wow what a difference. Trigger is now usable without a pry bar. I'm guessing it's now somewhere between 3.5 and 4lbs. versus a finger bending 7.5 to 8.5 that it was before installation. If you watch Lenny's video you should be able to install it yourself in under 10 minutes.

Double Diamond connector for G42..Great improvement over Glock OEM connector.


My buddy asked me to do something about his G42 horrendous trigger so I did some research and asked questions on Calguns. One guy said that the Double Diamond worked great for him so I gave it a shot. Installed it and the difference in the trigger was remarkable! Great product.

Got this connector for my Glock 48. Very simple to install, it made the trigger so much better. The pull is so much lighter then stock, well worth the money.

$24.99 can make a big difference!


Amazing what $24.95 can do for a Glock trigger. Big upgrade to the stock trigger pull. Took as long as the video to instal. Super easy and fast. Nice quality part. Two thumbs up!

Great product

Works great l. I can feel a noticeable difference in trigger pull. But I have no device to test the trigger pull so going by word of mouth here on this review.

Pure Butter!


Pure butter! This by far is the improvement made to my gen 3 23 by far! The trigger is so much better, smoother, crisper, and cleaner with a much, much faster follow up shots now. Accuracy instantly jumped to the point, that after almost two decades of shooting this gun, I almost had to relearn to shoot it again. Can't wait to put a pyramid trigger in it now to go with the premium double Diamond battle and other upgrades I've done.

Super smooth. Gets you to between 4.5 and 5.0 lbs on the legit trigger test.

This connector is super smooth and definitely reduces the pull. We tested it and it came up more than 4.5 and less than 5.0 lbs. Huge improvement for the price.
