I found this kit referenced in a blog after finding an old SW9VE buried in a drawer. Relegated to that drawer, unwanted and unloved, for probably 10yrs or so after firing it only a few times. After I found this old pistol, I wondered if there were any way to improve it and MAYBE want to use it again. I received the kit (extremely fast delivery time btw), I watched the videos on YouTube twice, and went after it. I really thought I would likely have to refer back to the video, but nope - super easy after watching the videos. Who would've thought that $13 would make such a HUGE difference?

MCarbo, only thing more I'd like to see is aftermarket stainless steel recoil guide rod/spring for this and Glocks (or all platforms)!

Thanks for being bad ass and making this tool useful again!

10lb factory pull

This pistol is just ridiculous from the factory. I had 10lb before the spring install. After installing the mcarbo spring and polishing internals it dropped to 8lbs. I however was not happy with the trigger pull but my coworker loved it. Waiting to retest trigger pull after 200 rounds to get final weight reduction measurement.

5ish pound pull

Made a difference on my SW9VE. It was a hard pull. Now it's smooth. Thanks for the fast shipping!

Does what the description says, very easy to install. Around 10min or so to install.

A Must Have

This really bought this gun back to a decent functioning pistol. It greatly reduced the trigger pull. I have not yet put it on a scale but would say it cut it in half. Best company I have dealt with as far as customer service and quick shipping!

Assembly tool was bad

Review

my assembly tool was nothing like the one in the video. it was too long to fit in the plastic housing so I had to sand it and it was too loose stay fit in the wholes of the plastic housing so it kept slipping out and the spring kept falling out. Ended up losing both of them after 30 minutes of it falling out.

Assembly tool was worthless

Everything went well until I had to use the assembly tool. It was too long to fit into the sear assembly making reassembly 100x more difficult.

Awesome

Ordered the wrong spring kit and when I reached out to Mcarbo they immediately worked with me to get my spring kit exchange to the correct one. Great company will definitely buy from again.



- as far as the spring kit goes, it definitely improved my trigger and made it much more enjoyable to shoot! Plus installation video on Youtube was super helpful, worth it for the price.

Awesome results! Must have!

This was an great improvement over the heavy as crap stock trigger pull! Well worth the effort and money! The instructions video is top notch! If you own this gun get it now!

Awesome Upgrade

If you have a sw9 or sw40 get this kit. The difference in trigger pull is night and day between stock and this spring kit. This literally cut the trigger pull in half and the reset and travel is so much better too. You can’t go wrong for $15 upgrade and relatively easy install once you watch recommended video, and your supporting our veteran brothers which is great too.

Big difference!
