Question: I wish they had more details on these things. Will this fit a Glock Gen 3 20SF?
Document: This trigger is great and truley reduces the spongey takeup on the front end of the glock trigger pull. It is much lighter than the factory 5.5lb trigger and the pull is shorter so is the reset which makes this far from a drop in piece. Trimming the tab for proper fit is easy, I used a dremel and filed it down until I got the fit I wanted.
Due to this not being a direct fit and requiring some modification, I am giving it one star. After I modified the connector, by cutting the excess metal tab off, it worked well.
The kit comes with all of the spring neccessary to do the job. Even though I did not need them, the instructions were clear and simple. I recommend this upgrade to anyone who hates the hard pull of the 5.5 LBS trigger on the glock.
This kit is probably the first thing that gets installed on all my glocks; granted that I don't mess with the safety plunger spring. Unlike the other 3.5lbs disconnectors, the Rocket will aid in over travel and reset length. Once the trigger spring and disconnector is installed, it drops the trigger pull to right around 4lbs and will definitely aid in accuracy over the stock trigger pulls.It will take some modification to properly install and there's a couple videos on youtube that help out.
Makes a huge difference on the pull of the stock Glock 22 I put it on. I tried to go old school and use manual file, but quickly got bored of that and switched to a dremel tool to grind the over travel tab down.
Their non-response is why I gave it four stars, as my weapon prior to the final adjustment was not performing properly.The trigger kit works stellar now, I am very happy with it and will get another for my comp gun and on the baby Glock 380 whenever I can get find one in stock.
I have a Glock 36 and the stock 5.5 pound trigger pull has been a challange to have consistant shooting. I replace the hammer spring with the six pound spring and after filing down the the bar in the kit, the trigger is smooth and crisp. The spot on the bar that has to be filed is tedious, however, well worth it.
WARNING!!!! This is not a drop in &#8220;Rocket Connector.&#8221; This did not drop right into my Gen 4 17 as advertised. I had to cut off a tab near the top portion of the connector. Remove your stock connector and compare to the one scene in the picture and you will see the extra metal tab I am talking about. Installing this connector straight from the box will not allow you to fire your gun.
This is an excellent and easy to install upgrade! While you'll still have the same long take before the trigger breaks, the trigger breaks cleanly at 3.5 lbs and stops, with no over travel to speak of. The reset is tiny, making for easy, fast strings.The instructions on the website are straightforward and easy, though there are also a couple of Youtube videos about the installation process that will actually make it easier for you.
Installed in my G35, world of improvement. Stock trigger was not crisp at all. Now it's crisp and light, aiding in first shot accuracy and follow up shots. Highly recommended for your Glock. I've had one in my G20 hunting pistol for around 7yrs; don't know why it took me so long to order it for the 35. If your on the fence, don't hesitate. It doesn't much at all to get it installed just right.
Answer: yes
