Just bought a slightly used DCAEK from a forum member and got to installing it today. Took me over an hour to get everything cleaned up, installed and reassembled. The hardest part is installing the USB (Ultimate Striker Block) which requires the removal of the rear sight.
Here’s the kit all laid out and ready to go :
Initial trigger pull weight is 5.5lbs
In the middle of the installation :
After installing, cleaning and polishing a little, here’s the new trigger weight:
Not only did it reduce the trigger weight a little, it smoothened out the entire action and lights up the reset. Now it feels like a smooth DA trigger pull, light break and noticeable reset. Not as much as a RAM (Reset Assist Mechanism) would, but good enough.
Now off to the range to test it out.
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.
Saw this video on Youtube posted by Brandon about the default trigger pull weight of a Gen4 versus a Gen3. He also talks about the possibility that this “could” be the cause of issues with the Gen4. What do you think?
Just installed some upgrades for my Glock 19 today :
Slug Plug – to plug the hole in the grip. I don’t know why Glock never bothered to fill this in the first place. WEIRD!
Stainless Recoil Guide Rod – this one is noisier than the stock polymer guide rod but more durable.
Extended Magazine Release – I also filed down the sides to give it a slight bevel so it won’t bite into my skin.
A Glock .25cent Trigger Job – basically polishing the metal areas to smoothen out the action. It works, just barely, you can tell that the trigger pull is slightly smoother, but you can still feel the polymer on steel drag during the pull.
A Scherer 3.5# Connector – Had to polish the heck out of this one. Look at all the imperfections. sheesh.
All done, except for the extended slide release which is on Backorder.
Just tested my 625 with the new improved trigger job and lightened spring on loads that I made using Federal Primers and it worked WONDERFULLY well. It lit every single round. I also ran my old rounds with the Wolf primers and it only lights up about 5/6 times. So one light strike for each moonclip. In the revolver competition scene, that’s a DISASTER.
Time to go home, load up more Federal Primer rounds and get some dry-fire practice in for this Saturday’s match.
Spent a few hours today working on my 625 JM and tuning up the trigger. I bought the Jerry Miculek S&W Revolver Spring Kit that he sells off his website Bang, Inc. and decided to follow some of his instructions on the Trigger Job DVD to smoothen the trigger action and associated parts.
I know this sounds dangerous and amateurish, yes indeed it is but what better way to learn about the gun than to try it yourself? If I screw up, then I’ll send the gun to Carmoney or Jerry to get it fixed. Consider it an educational fee
Here’s my original Trigger pull weight :
Here are all the pieces that I worked on :
and after fixing the action, polishing the internals and reducing the mainspring weight :
the action is much smoother, but I am still very skeptical. It feels like the firing pin will not be able to strike the primer properly. I have loaded all my revolver rounds with Federal Primers and seated each one very well but I still do need to test this out on the range, best way to find out.
What’s good is if it doesn’t work, I’ll just tighten the strain screw a little bit and test it again.
*UPDATE* Here is the 3 part series of my gunsmithing adventure!
