Hello group, I'm looking for "next step" direction on the following problem:
I have a Compact D to which I have replaced with the following CGW parts - 85 trigger with overtravel adjustment, reduced return spring, floating trigger pin, and short reset kit. After the typical first timer re-assembly issues, I got everything back together and off to the first range session.
After 2 mags, the trigger started to bind and would not return to reset without a nudge. Fired a couple of more mags and the condition did not change. Function of the firearm was otherwise fine, no FTEs, FTFs, locking into battery OK....
I have since taken this apart, polished more surfaces, and reassembled and still have the same trigger return issue. Some other problem symtoms I have noticed is that the is a lot of trigger take up after the gun has been de-cocked, and the new lifter is binding and will not move freely (yes, its spring is still correctly positioned). When I had the sear cage assembly out with the slave pin, the lifter arm moved freely ?
And direction on what I've done wrong, and need to do to correct, would be greatly appreciated.

I haven't worked on decockers, so I can't help much with those components. On the reset, have you checked to make sure the trigger bar spring arms are in the slots of the trigger bar? Sometimes they can get between the frame and the trigger bar.

The trigger not returning can be as simple as a lubrication issue. I don't know if you have oiled up the trigger pin, return spring or the sides of the trigger bar but the internals on these guns likes lubrication and especially the reduced power springs. I would first try to make sure you have plenty of oil on the trigger bar and trigger. Let it sit overnight after you lay the oil to it and see if that does the trick, if not you have some binding going on on one of these parts that you will need to track down.
On the lifter the lifter spring probably got some damage when the sear pin was driven in or again a lack of oil can cause it to bind. Oil it heavy and make sure the lube is worked into all locations and see what happens.

Thanks for the responses. I will reinspect with regards to both and report back.

Well, i checked everything out and everything appears to be intact and in place, including the lifter spring. I lubed everything thoroughly and let it sit, and while it seems better (getting trigger return), trigger pull should be smoother, at least on the return...and the lifter arm is still binding.

Did you disassemble or just look it over? If the lifter arm is still binding, I would disassemble the sear cage(again, sorry) and check the arm by itself on the pin. While it's out, take a close look at the lifter spring as suggested by SP01SHADOW.
While the sear cage is removed, work the trigger through its full range of motion to check for resistance. If that fails, maybe post some pics.

 

[Goju]

I did not disassemble but that is my next step.

If everything is not perfect the reduced return spring will bring it out. When you get the sear cage out check to see the the components are moving freely. The new lifter is sometimes thick enough to cause some slight binding of the other parts. I always polish each side of each component in the sear cage and the new lifter. It is stainless and will sometimes gall on the sear cage.

 

[Goju]

Thanks for pointing me in the right direction; I will report back after I get this apart and inspected with a keener eye.

 

[Earl_Keese]

Come on man take that sear cage apart again. Inquiring minds want to know what's going on inside!

 

[Goju]

I will Earl, have been away traveling and just got home today...I will get to it this week!

 

[Goju]

So I finally got back to this today and pulled the sear cage out. Lets just say I found the lifter spring to be in less than pristine condition - so that accounts for the lifter binding - or at least an obvious contributor to that problem. While I am waiting on some new springs to arrive from CGW, I will spend some more time polishing....specifically the lifter and contact areas on the trigger and the trigger well portion of the frame.

While you have the sear cage out, it's a good time to get a feel for how much drag is caused by the trigger and trigger bar. I usually work the trigger back and forth while applying downward pressure on the trigger bar(hammer and disco out of the way). Then let the disco catch the trigger bar(hold in place) and see if you feel any added friction. Does the trigger return all the way with the sear cage out?

 

[Goju]

Earl, when i engage or disengage the disco, I am not feeling any dragging or hesitation on the trigger return. If I disengage the disco from the trigger bar and apply downward pressure to the very rear of the trigger bar, the trigger returns but I can feel dragging.

Your probably pressing down a little too firmly causing the trigger bar to ride against the frame(under sear cage). Sounds like the trigger, trigger bar and hammer are moving freely. Sometimes there is some grittiness from the trigger bar spring riding along the tracks on the bottom of the trigger bar. When your spring comes in and you reassemble your sear cage, make sure everything rotates smoothly before reinstalling and you should be good to go.

In addition to the great advice you have been offered when you get it all back together it might be a good idea to adjust the tension on the trigger bar spring. If you have polished the TB and it is well lubed then one of the leading reasons for a slow trigger return with the lighter return spring and a gritty return can be cause by too much tension under the trigger bar. Try adjusting the TBS so that you have about 1/8" of the spring sitting above each side of the trigger bar when you un-clip it from underneath the bar. Too much tension under the TB causes a stiff gritty double action, a slow return and various other problems in the action. You only need enough tension to hold the TB against the bottom of the sear cage, anything more is too much.

 

[Earl_Keese]

Hey Goju, any progress?

 

[Goju]

Actually yes. Earlier this evening I put everything back together and I am not experiencing any trigger return problems - at least prior to actually getting some rounds down range. I noted Shadows suggestion and checked the tension on the trigger bar spring. It seemed like the left (control) side of the spring was exerting more pressure on the trigger bar than the right side, so I tuned it for uniform tension. Prior to this final assembly I lost a new lifter L spring An earlier reassembly attempt, and had to rebuild the entire sear cage assembly...a good character building exercise. I will have to get a couple of hundred rounds reloaded and fired to proof functionality. The original problem showed up after firing less than 50 rounds. Thanks to all for your help!!

 

[SPO1SHADOW]

If shooting it causes the problem to return I would suggest looking at the trigger bar spring again with the grips off to determine if the top or tops are jumping out of the grooves and trying to get between the trigger bar and the inside edges of the frame on each side. If the trigger bar spring is bent too wide it won't stay in the little grooves and will pop out to the sides of the frame causing a slow gritty return.

 

[Goju]

I will make note of that, thank you. I have off of work next week so I should be able to get some loads worked up and some range time in...everything is taking a backseat to bird hunting right now
