Perfect

Rating:
Pros:
Cons:
The first gun that I ever purchased was a Mossberg 500 and I've made upgrades from stock to choke, and the I've always wanted to improve the trigger but wasn't aware of any trigger upgrades. After some research I found MCARBO and this kit is superb. BY FAR worth the $20 to improve the trigger, drops the weight of the pull and makes it smoother in the process. If I buy another 500 I'll DEFINITELY grab another MCARBO trigger spring kit. The fact that MCARBO also puts together simple, informative installation instructions is a bonus and a reflection of their high standards for customer service and satisfaction. I'd give them 6 stars if I could.

I bought this because my 500 had a light firing pin strike. A previous review said this spring corrected the issue. Yes it does correct that problem!
