I have a M&P 45 4.5 with regular and threaded barrels. I also have a M&P 9.

The 9 has a decent trigger that is useable. It breaks a little ahead of the over travel stop, but again it is usable. Trigger weight averages about 6.2 pounds.

The 45 is a different beast all together. It breaks right at the over travel stop. If you put a paperclip between the trigger and the stop it will not break. Weight averages around 11.9 pounds. I think some of the weight may come from it touching the over travel and basically bending the trigger in the middle.

I wanted to do a APEX kit for it, but read that it moves the overtravel back. If anything i need to go forward 1-2 tenths of an inch. I have read about it possibly being a MA compliant gun. I will get the SKU off the box tomorrow.

I am eyeballing the trigger bar and wondering if there is any adjustment that can be made there.

The 45 is basically worthless as it is. I shoot double action revolvers alot, but cant shoot this one without the front sight being pulled to the right. Up and down strings are about 1 inch, but left to right (all right of the bullseye) string about 6-8 inches. The 9 shoots about 1.5 inches at 15 yards all day long.

I am hoping someone has had this issue and found a way to resolve it.

Factory spec on these guns is 6.5 pounds but I have heard of .45s being heavier, one of mine was 7.5. If it is not a Mass compliant gun I'd call S&W and sent it back for service. That sounds not just heavy but faulty to me.

Sounds like you need to open up the trigger bar loop that contacts the sear. Opening it slightly but in very small steps. I would do this prior to purchase or installation of other parts.

Be certain to get an Apex Sear for the 45 as the 9/40/357 sear would exagerate the loop problem.

Thank you TOF. I found a video from Apex on how to do that and sure enough it helps a bunch. I am still going to get a apex kit, but it gives me peace of mind that it will work.

Thank you again!

I too had the same problem. I simply installed the Apex DCAEK kit and it solved the trigger pull problem. I would recommend getting the Apex RAM for M&P45's when it becomes available. It will give you a more audible trigger reset as well as a few other fail safe features.

Just wondering how old it might be ? I have an older model with zero issues. It this a newer model ? I was thinking about getting a mid size and wondering if the newer ones might have an issue.
Thanks.
