I bought and installed the springs on my Mossberg 535 a while ago. Technically it cut the pull from about 6.5 to 4.5 pounds. I just tried it out tonight, it shoots a lot smoother and easier.

Ordered these springs and they were in my mailbox within 8 days (Canada). Even got a few follow up emails checking in to see if I got my springs and also installation instructions.



My 590A1 factory trigger pull was 6 3/4lbs. After installing the MCARBO springs while keeping the secondary firing pin spring, trigger pull dropped to 6lbs.



Removing the secondary FP spring, trigger weight droped to nice 4 3/4lbs.



I haven't shot my 590A1 with the new springs as yet but I haven't seen anyone complain about light primer strikes so I'm not expecting to have any issues.



Hats off to these guys and thank you for your service.
