Unless that release has a new type of sear and cam, when the release cams are under the pressure of a fully drawn bow, you do not get a trigger-pull as you would on a firearm. Regardless of how the cam/caliper is designed, I do not recommend trying to pull the trigger as you do on a firearm.

I determined a long time ago, that trying to pull the trigger on a finger release as I would on a firearm put to much tension in my hand and I had to concentrate on the pull to get the damn thing to go off. BAD! A release should almost surprise you when it releases the string.

My releases are set so that I can wrap the tip of my shooting finger over the trigger, but not get a pre-release. When my pin is on, I apply a bit of back tension and the release will fire. Although I know what is about to happen, this back tension method still causes a bit of surprise when the string releases.
