Custom TM Hi-Capa Not Hammer not locking back

[gerardcb]

I have a custom hi capa with these parts:

Guarder Marui Ops Dual stainless 5.1 slide,
Guarder 5.1 metal outer barrel,
Custom 210% recoil spring
Pdi compensator set,
6.01 7inch barrel,
Guarder Bushing,
150% hammer spring,
Airsoft Surgeon Stainless Steel Disconnect Set

I just put in the new Airsoft Surgeon Stainless Steel Disconnect Set, but it still doesn't lock.

Check your leaf spring prongs if they are set right on the sear.

Have you tried observing the sear movement? You can remove the rear grip safety spur (dingus that your thumb wraps around) to open a space so you can directly observe the sear and hammer engagement. The 1911 series of pistols is fairly easy to troubleshoot because of this feature.

You can simulate the recoil cycle manually actuating the slide and hammer with the following scheme: mag with no gas or bbs loaded!

starting conditions: rack slide to cock hammer and allow slide to return to battery

1. pull trigger to drop hammer, MAINTAIN trigger pull (keep the trigger depressed)
2. keeping pressure on trigger, slowly rack slide and observe sear movement while hammer is being re-cocked
3. observe disconnector movement to see if trigger bar is being decoupled after first third of slide motion
4. fully rack slide and slowly allow it to return to battery
5. observe sear engagement with hammer on forward stroke

It is important to maintain trigger pressure throughout the cycle to properly simulate the practical recoil cycle. The recoil cycle is very fast, a typical trigger pull will have you applying pressure throughout the entire recoil cycle instead of letting go at the exact moment of hammer release.

I suspect that either Hitman is correct in questioning the leaf spring placement (usual problem) or that you have a disconnector related issue. It's possible that an improperly sized disconnector tang or bent trigger loop could prevent the hammer sear from properly re-engaging the hammer with the trigger pulled.

Sometimes the hammer stays back when returning the slide to battery slowly, but snaps forward when the slide is released rapidly. If this issue is sporadic, it is often caused by the disconnector not being pushed down far enough to disengage with the sear or friction in the sear pivot. You have to be very careful when installing aftermarket trigger/sear related parts. There is often a bit of fitment involved to get things cooperating just so.

Thanks so much guys. It helps alot. Right now, I'll tackle one problem at a time.

One problem you suggest is the leaf spring placement.

I would think that if I'm able to the the gun back together, then the leaf spring should be put properly right?

I'm not sure what the proper way to put the leaf spring in. I just saw that it fit perfectly' so i assume that it is in properly.

Thanks!

The three fingers on the leaf spring should lay over three separate components if it's correctly installed. From left to right (with upright gun pointing away from you):

-disconnector
-sear
-trigger loop

It is possible to put one or more fingers behind the disconnector and sear and have the gun go back together. Both of these parts needs to be pushed forward by the leaf spring.
