GUN TESTS, Trigger Upgrades

HIPERFIRE comments: Both the EDT and 24Elite triggers were reveiwed with different overall scores and comments. The EDT design is identical to the 24E less the toggle spring system. The only difference in feel is due to the difference the trigger weight settings make, which is especially true during break-in. In the case of the 24E, the break in period is slightly longer for the weight to become consistent, 100-200 dry fires (breaking through the Parkerizing, then self polishing begins).

Initial weight and feel is also a strong function of spring break-in, especially the hammer spring. After any of the springs are formed, they are heat treated to remove residual stress. The wire surface becomes noticeably rough. Wires that slide on one another exhibit noticeably high friction. The hammer spring is a double-torsion spring. When the hammer is cocked and when the hammer falls, the coils slide on one another. Initially, this sliding friction is very high. This will contribute to variable trigger weight measurement during initial hammer cocks and falls because the hammer spring supplies all of the force on the sear. This hammer spring effect is especially operative on the 24 series triggers, which share the toggle spring system, which makes for a more sensitive tactile feedback that many shooters desire. During the 100-200 dry fires noted above, the hammer spring friction effect is eliminated after repetitive sliding of the coil wires has developed self polished interfacial surfaces. It is not expected that any reviewer would be aware of these facts. Nonetheless, it might have affected the review findings or perceptions.
