Fitting a 1911 Trigger

Recommended Posts

1. What can you do if an oversized trigger just falls in out of the box and is loose ??

SVI trigger, STI Spartan ...

2. I've only put them in on 2011's and plastic is very smooth, now on this cast Spartan, what would be the

"proper" way to clean out the bow track in the frame. I could feel a little grit as the bow would rub. I reshaped

the bow a little and covered it with lapping compound which showed the slight high spots right away but what is

the official technique ?

3. Also I'm usually putting an SV trigger into an ST frame and I always need to tweak the angle of the back of the bow,

lessoning it, to better match the disconnector, is this correct ?? Otherwise it sort of slips up and down and you can feel

a slight bump in the pull ... :unsure:

Here it is:

I finish polishing with a Q-tip and simichrome polish. I also polish the trigger on all sides and the bow--especially where the disconnector rides.

ETA: The trigger fitting gauges from EGW come in handy when you're fitting an oversized trigger:

Oh !! That is exactly what I was trying to find around this house !! :roflol:

Who new ?? There's a tool for everything !! ;)

What about bending the back of the bow, is that right ? If it is then why are they always at that angle ??

Use a punch or chisel to move metal on the trigger.

It's an aluminum SV trigger, what are thinking, squeez it until it's taller ??

Works for me... oh wait... only for a few minutes... :roflol:

BTW... JB weld MIGHT work... I've used it on pneumatic trailers that operate at 15 psi internal to seal up minuscule cracks...

Don't know if it would hold up to the constant rubbing in a trigger job though...

Matt has the right idea... tig weld a little metal on there... then fit it in...
