The triggers are ready to go when installed correctly-. However, the initial feel will change over several tens of dry- or live-fires. Why is this?
The triggers are finished with a MIL-spec process called Parkerize, or heavy Manganese Phosphate, as a rust preventive finish (except for the TH24 with the special Nickel plating). When the trigger is pulled and breaks, releasing the hammer to strike the firing pin, the trigger and hammer sear surfaces scrub off the Parkerize exposing the bare metal. During the process, the feel will change slightly. In fact, initial measurements of trigger weight are unreliable for this reason. But, after 100-200 cycles, the feel and weight will stabilize as the sear completes the self polishing process.
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 friction 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.

The trigger pin walks out because it is not captured by one of the hammer spring legs. This can happen in two ways and yes, it can be fixed.
- The hammer spring’s legs don’t seat in the slot made for them on either side of the toggle FRAME so they can’t rest in one of the trigger pin’s grooves and retain it. Fix this by making sure they do. If that doesn’t work, read on.
- The TRIGGER SLEEVE has not been rotated so that its notches match or line up with the notches on either side of the FRAME (this was noted in the installation manual and in the online installation videos). To fix that, take out the trigger subassembly and inspect it. If the SLEEVE is out of alignment, squeeze down on the disconnetor to release some clamping pressure on the TRIGGER SLEEVE and rotate the SLEEVE with a tool or your finger nail until alignment has been established. Now the hammer spring legs can lie in the trigger groove to keep it from walking out.

Safety/Selectors: HIPERFIRE® knows of six safety selectors that will not work with HIPERTOUCH® 24 series triggers:
- Seekins Precision Ambi Safety (60 and 90 deg throws)
- V SEVEN HYBRID 3 GUN/SPORT SELECTORS
- Elftmann Slide Safety Selector
- Talon Ambidextrous 45/90 Safety Selector
- BAD-CASS or BAD-ASS Short Throw Safety Selector
- KE Arms Ambi Safety Selector (45/90 deg throws)
HIPERTOUCH® 24 Series Triggers
The frame component of the HIPERTOUCH® 24 FCG that provides the toggle spring system support is designed to ride on the barrel of semi-auto or “MIL-spec” safety/selectors (not full-auto). This permits normal functional rotation of the safety/selector. An aside: when the FCGs are first installed, some users will notice a little grit during rotation, which is a function of the surface finish on the safety/selector barrel. With a few cycles it will smooth out as the frame and safety/selector self polish.
The ambi safeties listed above do not have a large contiguous cylindrical barrel surface like the stock version; two or more channels or a small diameter barrel have been cut into them that accepts the rear of the trigger when pulled into over travel. The toggle spring frame drops into these channels, which not only relieves necessary compression of the toggle springs but may also prevent free rotation of the safety/selector or even cause rotation of the selector during repeat fire as in the number two case above.
HIPERTOUCH® EDT Series Trigger
The Seekins works in 60 deg throw mode in SAFE and FIRE w/o issue. However, in 90 deg throw mode, the trigger will rotate enough to release the hammer. This is because the trigger tail is shorter than MIL/stock triggers and can move up into the exposed Seekins SS slot just enough to release the hammer when pulled.
Other Ambi Controls: The ambi bolt catch on S&W M&P10s interferes with free rotation of HIPERTOUCH® 24 series triggers. Users have simply removed the ambi control and restored proper function of the 24 series FCG. Some safety selectors, such as the JP Adjustable/Reversible Safety Selector, have adjustable set screws and locking screws that eliminate sear/trigger travel. HIPERFIRE® recommends you review the selector manufacturer’s installation instructions to ensure proper selector function.

The HIPERTOUCH® family of triggers were designed to function with a consistent feel whether lubricated or not, i.e. for the worst case, when proper maintenance and lubrication are impossible: the battlefield environment. HIPERFIRE® has live-fired triggers in excess of 100k rounds without lubrication, without hiccup, or change in trigger feel. This is because the sear contact surfaces are large and robust in the first place, limiting excessive wear, and in the second place carry lighter contact impingement loads than competing products due to the addition of the toggle springs. Since the sear load is reduced, the wear is reduced.
Theoretically, using lubrication will increase product longevity versus running the triggers without lubrication. Good lubricants will make clean up and maintenance easier as well, but will not significantly improve feel. Why? Lubricating films generally improve lubricity when the contact surfaces are mutually large and in close intimate conformal contact. The film between these surfaces is pressurized to some slight degree (a function of the lubricant’s viscosity among other factors) and prevents or inhibits metal-to-metal direct sliding, thereby reducing the friction coefficient and reducing wear. However, in every fire-control design including HIPERTOUCH®, the trigger sear edge and not a broad conformal surface interacts with the hammer sear surface so that film pressure, for practical purposes, is nonexistent, i.e. the difference in pull weight between lubricated and non-lubricated HIPERTOUCH® FCGs is insignificant.
Having said all that, any lubricant will extend wear life.

This chart was constructed from test data that HIPERFIRE® generated to compare hammer fall energies of various products to HIPERTOUCH®. Three different measurement bars are shown for HIPERTOUCH® triggers representing the installation of the three different toggle spring pairs that come with the products. The spring pairs determine both trigger weight and hammer fall energy. Only one “Top Product” competitor has a hammer fall energy that exceeds the lowest of the two HIPERTOUCH® hammer fall energies. The remaining competitors are decidedly lower in energy, due in large part to employing very low hammer spring power required to meet their goal of lowering trigger pull weight.
The highest hammer fall energy among all the products tested, including the two MIL-spec triggers tested, were the HIPERTOUCH® 24 series triggers with the plain toggle spring pair installed. It provided for both low trigger weight and high energy hammer fall.

HIPERTOUCH® triggers install in modern sporting rifles (MSR) such as the ubiquitous AR15 and its many multi-caliber variants. HIPERFIRE®’s single-stage, semi-auto, Enhanced Duty Triggers (EDTs) and the 24 series of triggers all operate on the same principles like user-adjustable weights and high hammer fall energy, but with some important differences. The charts below summarizes these key features:
- All the products have 3 or 2 basic user-adjustable trigger weights shown in the top line by the 3 different colored toggle spring set ups in the case of the 24s and 2 different colored hammer hammer spring set ups in the case of the EDTs. The 24C and ECLispe have 5 shoe positions, so they have 3×5=15 different adjustment pull weights. The colored dots on the weight scale correspond to the springs installed by color.
- All the triggers have the highest hammer fall energy of any AR trigger anywhere when using the gray toggle springs (24s) or the red hammer spring (EDTs) and near stock hammer fall power when the others are installed The hammer fall energy is compared to a stock or MIL-spec trigger set up shown in green by and further scaled by mini-bar charts.
- The next three lines highlight specific design shape features.
- The next line, Pre-Travel of Initial Pull, shows how much “creep” is in each HIPERTOUCH® trigger (creep is defined as the distance, or feel, of one metal component sliding on another). This is then compared to a stock or MIL-spec trigger and among one another other using a horizontal, green, baseline, mini-bar chart representing the stock or MIL-spec trigger.
- Importantly, the Pre-Travel from Hammer Reset, shows the amount of creep compared to the creep of the initial pull, i.e. the creep to expect after taking a shot, letting off the trigger and taking a follow-up shot at the point of hammer reset.
- The last line shows the type of cartridge the triggers can handle. The last column shows that an optional spring combination (green toggle springs and red hammer spring) that can also handle 762×39 Russian rounds, which have notoriously hard primers w/ 100% ignition, i.e. no light strikes. Of course, the triggers can also handle 300BLK, 22LR, 9mm, etc.
Again, it’s only a summary. Getting your finger on one or more of the triggers will tell the rest of the story. Contact us if you want more detailed information.
