I wanted to lower the trigger pull weight on my CZ 457 Varmint. I had it adjusted as low as it would go and it was at 2.6 lbs and nice and crisp after adjusting both the creep & over travel settings, it was pretty good actually. Anyway, I took the spring out of a Bic lighter and measured it and it was within .001" of the diameter of the original CZ trigger spring. I cut the Bic spring to the same length as the CZ spring and installed it, tuned the creep & overtravel adjustments accordingly then worked the heck out of the action while preforming "drop tests", very vigorous action cycling, safety on/off and whacking the action with a rubber mallet. Trigger never released once and now breaks at 13 oz and is very crisp, as in zero creep and over travel. Huge improvement and works like a hot damm. Have shot it a lot with zero issues. UNDER NO CIRCUMSTANCES DO I RECOMMEND OR IMPLY OR SUGGEST THAT ANYONE DO THIS.

The 457 does have a very nice trigger, especially with a spring replacement.
Hard to justify an aftermarket trigger for them, though they are out there.
13oz would be too low for me, I like 1.5-2lbs
