CZ SAO trigger replacement for TSO - different TRS?

[MuayThaiJJ]

I ordered a new CZUB SAO flat trigger for my TSO. Does this use the normal Trigger Return Spring for CZ75's?

I hope so because I plan on installing an extra power TRS.

The trs for the tso/ checkmate is different from the regular trs. The trs for the tso serves 2 purposes, for trigger return and trigger bar tension. 
 

thank you,

i didn't know they make a heavier TRS for the SA triggers.

i would check on the spring.

I don't think so, I think the was referring to a spring that's the same as a 75B/SP01.  But for a TS the spring is different.

no problem. it will work. but u will need use both springs.

Personally I would not do that. Because there is no need to complicate such a successful system.

Please tell me what’s going on in this pic. Both types of springs?

[yigal]

yes.

Awesome, that's what I am going to do in combination on my TSO: Tanfo sear spring, CZ-75 heavy TRS, and TS oem TRS to increase trigger pull and give a more definitive reset and break with a CZUB SAO flat trigger.

Ok, almost there. I did the dual spring on the stock TS SA trigger:

the use of two TRS is a trick idea. 

i was thinking about making a heavier return spring for the SA trigger but never had the time.

this is a quick way for a heavier reset.

how much do you think it effected the reset ?

It feels a lot more positive
