Have a look at the new Mag-Tek line they have no springs and can be adjusted from light,medium and heavy trigger by the turn of a screw driver.

Designed by Ken Stanislawski so you know its going to be a good release.



Here is what they say about it on their web site.

HOT SHOT and MAG-TEK is proud to announce the MAG-NIFICANT 7 This is a release using a solid permanent magnet. No more worn out or weak springs. This caliper has a machined aluminum body and case hardened sear and trigger mechanism. The trigger rests against the magnet, as you squeeze the trigger it breaks away from the magnet allowing the sear to open. The magnet is also utilized to help pull the sear open. Neither of the two moving parts are ever pushed to the edge to obtain a crisper feeling trigger, making it safer to draw back and therefore eliminating the occasional misfire. This gives you zero travel and superior trigger feel. If you’re pulling the trigger and let up nothing has moved, totally eliminating misfires. to adjust pressure you loosen the set-screw and rotate the magnet until you get desired tension then retighten the set-screw, then your ready to shoot.
