What is camming?

[Niel4]

I read people refer to trigger camming....what does it mean?

Niel4, I grew up in St. Louis (and other parts of the midwest) but I have never heard anyone refer to "trigger camming" before. Are you perhaps thinking of the phrase "trigger stacking"?

As I understand things...

Camming is used to describe the hammer motion relative to the trigger. Some pistols have hammer/sear angles that 'cam' the hammer back slightly as the trigger is pulled. These angles help ensure that the hammer cannor slip off the sear unintentionally. This can lead to the sensation of trigger 'stacking' (in which the pull effort actually increases as the trigger is pulled) but commonly does not. In sum, trigger stacking can occur without camming, and camming can occur without trigger stacking.

Exactly. AKA "positive hammer engagement" or "hammer camming." If you want to see this in action, dry fire a CZ75.

Thanks....I have a cz 75 so this will be easy!

Being sure to observe all safety rules, cock the hammer and watch it carefully as you slowly pull the trigger. There will be a takeup or feeling of slack, during which the hammer will actually move back slightly before the end of the takeup is reached and the hammer actually falls. This is the one criticism I have of my own PCR Compact, as this takeup is accompanied by roughness and "creep", but I am loath to mess with it.

I was just going to say that even though I know nothing about camming as it pertains to triggers and hammers, based on rbernie's description it seems like a CZ75 would have it.
