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

I recently purchased a Mossy 930. I ordered this part straight away. I have the MCARBO spring kit in all my M500 variants so I figured to try it in the 930. It did make a difference over the OEM spring. Good value for the money.

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 checked the trigger pull with the stock spring and it was 5.5 pounds and when I put the mcarbo spring in it was still 5.5 but it claims it should take it to 3.5

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!
