I put this on my Mossberg 930 Pro-Series Sporting which had a decent trigger right out of the box and for the first time I could not tell a difference after the MCARBO part swap. It still has a decent trigger so I can not knock it especially as I am just gauging it with my finger and not an instrument.

Compatible with 940 PRO TACTICAL

Installed it minutes, same procedure as the 930. Got a solid average 3.5lbs pull on my bench using a simple Wheeler Trigger Pull Scale. Took my 940 to the range, shot around 50 slugs with no issues, trigger feels amazing!!.... $13 WELL SPENT!!!!

Crisp!

Really nice add on to a factory shotgun, specially a semi-auto. Grease the striker like instructed and wow you've almost got a nice crisp riffle trigger. Customer care goes above and beyond with MCARBO.

Deer Slughunter - easy and effective upgrade

Easily the best upgrade out there for my 930 auto slug gun, replacing the trigger spring. 2 pins, assembly drops out, use a snall flat blade screwdiver to compress old spring and pull off. Clean and oil assembly, replace spring and lube the sear with the grease MCarbo offers. 15 minutes tops, most time is spent cleaning and lubing. You're left with a smoother, less creepy, easier pulling trigger. I am a deer slug gun hunter, this is a no-brainer and did the same for my 870 pump back up/carry gun. I am very happy wuth this upgrade.

Does exactly as advertised

Worked out great, simple to install, in just minutes. It flat out works, my trigger is a pleasure to pull now. I laid a little bit of trigger lube I use on my other guns on the sear .... can't wait to shoot again. Before the spring, it seemed like it took way too much pressure and effort to squeeze the trigger. Now, I just put a little squeeze on ... and it goes bang! If you don't have trigger lube in your tool box ... don't blame MCarbo!

Easy installation.

I have a mossberg 930 jm pro. I measured between a 5 and 5.5lb trigger pull before. And a 4lb trigger pull after. So I am very happy. Any lighter and I might be worried during competition.

Easy Peasy

This was a very quick installation/upgrade. It took all of five minutes. Now my 930 has a really slick easy trigger pull. I do not own a trigger pull gauge however I can tell the trigger pull is smoother and lighter. Way to go M-Carbo.

Easy results!

Review

Note this is the only MCarbo spring replacement I have installed that did not reduce my trigger pull. It was 4 pounds before and 4 after. My conclusion is that the prior owner installed a spring kit in this shotgun already. I have installed MCarbo kits in several pistols and they are always easy to follow videos and resulted in reduced trigger pull force.

Easy, Fast and works

Fast shipping, easy installation, took my 930 from 4.5 to 3.5 pounds. A little polishing and I now have a nice trigger.

Really goodExperience dealing with the company.

Thanks for the good communication and follow up.

The spring worked out great and installed easily.

Really reduced effort and should come in handy especially when shooting magnum loads in the 935

Just a constructive note: it may be good to note in the detail of the info for the spring that it is recommended to use the grease. For the reasonable price it costs think many that do not have any on hand would gladly order for the 2-3 dollar cost ( win/win situation)

Thanks again- great product and company !

Excellent Product !

I was searching for a product to upgrade my Mossberg 930 trigger pull and I was able to find one at M carbo.

After receiving the spring I was able to install this trigger very easily and quickly.

The customer service provided by Chris and Bobby was excellent and beyond expectations.

I can't wait to try out this new trigger and look forward to future business with M carbo.

Thanks again Chris and Bobby !

Excellent Product and Service!

Excellent Upgrade to the Mossberg 930 Trigger Group

Review

I found this upgrade to my Mossberg 930 SPX's trigger group to be excellent! Trigger pull is noticeably smoother and lighter without being too light for my purposes. The weight of this spring is well chosen and appears to be manufactured of quality materials. Yes, it's a spring and a fairly simple part not to mess up but, I have seen poor quality springs just the same and this is not one of those for 100% certain. I also bought and used the PTFE Synthetic Grease for the sear engagement contact points and that worked well in combination with spring in smoothing the trigger pull. Glad I bought and extra tube to use on my other triggers. Great products M*CARBO Team. Thank you!
