Trigger Creep?

[TMan]

I'm not sure I'm using the right terminology, but let me define the terms I'm going to use with my definitions:

"Take-up" doesn't come into play so much in SA, but in DA/SA like the Sig P220, when the hammer is cocked, there is a large movement of the trigger before resistance is felt.

"Creep" is after resistance is felt you apply more pressure and feel the movement of the trigger (usually it feels gritty) then it goes bang.

Two guns I have are similar in size and looks, but very, very different inside, are the Browning Hi-Power, and the CZ-75. The triggers feel completely different. Of course I am comparing a SA to a DA/SA, but all I'm interested in is after I feel the resistance.

THE BHP has a fairly heavy trigger pull, but no creep. You apply pressure, more pressure, more pressure, suddenly it goes bang.

The CZ-75 is creepy. After you feel resistance you pull, it moves, it moves, it moves, and then it goes bang.

If you consider the engagement between the trigger and sear, it seems to me as you move the sear, you should be able to feel it like you do on the CZ-75. However, on the BHP you never feel any movement.

What is going on? How do you eliminate the creep?

TMan; How much the sear moves, after having pressure applied through the movement of the trigger, is a good measurement of creep. The surface contact being the sear and hammer hook should be smooth enough to where the two metal to metal parts do not grind against one another. Eliminating the amount of movement of the sear to the hammer hook engagement , in order to release a cocked hammer, might compromise the safety of a carry pistol.
Pressure from a heavy mainspring to the hammer will also contribute alot to creep, especially if the surface of the contact between the sear and hammer hooks is not prepped by stoning and polishing.
I always apply a very small amount of lube to the sear to hammer engagements to preserve the integrity of an already good trigger system.
