Your mcarbo trigger spring made a noticeable difference on my 930SPX. Peel 8 shots of as fast as you can press the trigger. The follower is a quality improvement too. Thanks Chris!

I used this spring in my new Mossberg 940 Pro Turkey. It is the same trigger group as the 930 and it really helps with the heavy factory trigger pull. I lost the tips of my trigger and my middle finger on my dominant hand. If it wasn’t for this spring I would have to switch to shooting with my none-dominant hand. I plan on using one for all my Mossberg shotguns

Thank again

Om my particular shotgun, the factory trigger pull was 5 lbs. 15 Oz. and after the spring replacement it was 5 lbs. 2 Oz. both measured 3 times and averaged by my Lyman trigger gauge. The installation was easy and the price was right. This is a brand new gun so maybe it will reduce some.

I ordered the mossberg 935 trigger spring kit. Then watched installation video. After watching video I then ordered the grease Chris used in the installation video. Installation was very easy and straight forward. Definetly lightened trigger pull. Due to the gun being new there was some dirt or something down in the rest of trigger assembly I sprayed it out with some action cleaner and then some light oil and the trigger improvement was even better. I would recommend ordering the little tube of grease when you order the spring kit. Great upgrade for little money just like everything else I have used from M-Carbo.

I bought the 930 trigger spring hoping it would work on the new 940. As it comes, the spring is a little to long. I cut one coil from the new spring and my trigger is now just over 3.5 lbs.

Bought this to lighten up trigger pull, supposed to be in the 3 1/2 pound range from the 5 pound factory trigger will see haven't had time to install yet, over time cause people DON'T want to work so somebody has to. Price I thought was very good and the shipping is spot on quick. Will be getting part for my Kel Tec KSG later. Thanks M*CARBO.

This was a quick drop in. My Mossberg 930 Tactical SPX trigger weight went from a consistant 5.5 lbs to 4 lbs.

Just follow the video and do not release the trigger. Life will not end but there will be a learning curve. I own 2 binary triggers and this is no binary trigger. The good news is, it don't cost $400.00 Bucks. I was truly amazed at trigger response after installation. Definite improvement. If this spring holds up, this will be one of the top purchases of my gun loving history. Thanks! M*CARBO Bro's!
