S&W Sigma SW9VE & SW40VE Trigger Spring Kit The major complaint with the Smith and Wesson SW9VE / SW40VE is that is has a very heavy 9-10lb factory trigger pull. This leaves a lot of us looking for affordable SW40VE Accessories to make further...

Kit and video we're self explanatory. Reinstalling the spring and pin at the end using the supplied dowel was a bit challenging as the dowel kept slipping allowing.the spring to fall.out of place. Used a small punch to hold spring in place and inserted pin from the other end, which worked out fine. Definitely lightened the trigger, looking forward to sending some rounds down range.

Just had the chance to install the new spring. My opinion is that the spring and video are super high quality. The install went very smooth with the help of the video. The challenge that I had was that small dowel included with the kit although very helpful was too long, I had to snip it shorter. The end result was a MUCH improved trigger pull and it was exactly what I wanted. I will definitely use MCARBO in the future and recommend them.

A little tedious to install, that's why the video is so helpful. Very inexpensive solution to a hard trigger. Made a world of difference. I can actually shoot with confidence now without torqueing the gun when pulling the trigger.

The trigger pull won't knock your socks off but it is much, much better. We all know how bad that stock trigger pull is. With that in mind, this item is worth every penny. Excellent instructional video. FAST shipping. These guys respect their customers and it shows.

I just finished installing the new SW9VE trigger spring. This is my second or maybe third purchase from MCARBO. You guys have the best customer service; high quality products and superb easy to follow installation videos. (Excellent job Chris) I will definitely use MCARBO in the future and absolutely recommend you guys.



Question; do you guys have a solid Firing pin retaining pin for CZ75 compact?

This was a simple upgrade to improve the trigger pull. My wife really hated our SW9VE before this change, and she is now looking forward to being able to go to the range and put some rounds on target. The shipping was very fast and the video was very helpful.

I had a reputable gunsmith install this lighter trigger spring. Before installing the new spring, he took 3 pull measurements averaging about 10 pounds. After installing the new spring, the 3 pull measurements averaged about 9 pounds. I spent $19 for the new spring and $65 for the gunsmith for a total of $74 and only gained a 1 pound improvement. I'm extremely disappointed with this product.

Very much like the results. Trigger pull reduced significantly. Unable to install last spring. Went to a gun smith who used a punch to do the alignment and retention of spring.

Pig tail spring was very difficult to install. Spent hours on it and then went to gun smith. The gun smith struggled with it but was able to finally install it. Interestingly the '"sigmatrigger kit" does not reinstall this spring. The trigger pull was much better.
