A friend of mine just picked up a new Smith and Wesson M&P 45 recently for a good price. I suggested to change the sights and improve the trigger with the Duty/Carry Action Enhancement Kit (DCAEK) & Ultimate Striker Block (USB) Kits from Apex Tactical and go to work to help out with my mediocre gunsmithing kung-fu.
here’s what’s in the kit :
The standard trigger is HORRENDOUS. I can’t imagine Smith and Wesson selling a product with such a crappy trigger, when the fix is so simple. If you look at the kits that Apex Tactical sells, those are just replacement parts which Smith and Wesson can just make on their own.
At 7.5lbs and trigger pull is super gritty. It feels like you’re dragging a small rock wrapped in sandpaper as you pull the trigger back, before having to exert so much pressure to release the sear. My double action revolver has a smoother action than this! IMHO of the three popular plastic guns, the XDm ranks highest in terms of trigger feel in a stock gun, Glock next and the M&P at a distant third.
So first things first, install the Ultimate Striker Block, which makes the trigger pull a lot smoother because it replaces the stock striker block plunger with one that’s nicely beveled and polished. This modification alone makes the trigger pull smooth.
In order to add this part, you’d have to remove the rear sight, so I took the opportunity to replace the stock white dot rear sights with a Warren Tactical black rear sight.
I didn’t take many pictures of the process but here’s the result :
VERY smooth trigger pull, shorter reset, and crisp 5.25lb break. nice! can’t wait to take it to the range.
Here’s how it looks, beautiful! Wish I had one.
