Aftermarket Triggers:
Many Shocker triggers have been released over the years, although most of them are no longer made at the time of this writing.
Generally, manufacturers will use a similar design and hardware for any variation they make. For instance, set screw threads will be the same, position of adjustment set screws will be the same, etc.

Smart Parts SFT stock trigger The Shocker stock trigger uses a slim "blade" shape. No Smart Parts triggers had bearings until the Shocker NXT was released in 2006.

Smart Parts Nerve stock trigger The Nerve stock trigger uses the same design as the Shocker SFT, but a "double" trigger shape on the front. Nerve triggers were unveiled in 2004 and were available from some retailers that had access to SP's inventory, but they weren't available as aftermarket parts.

Smart Parts Nasty trigger The Nasty trigger came stock on Nasty Shockers and Nasty Nerves. These triggers use a "beavertail" shape which gets wider further down the trigger face, which was very unique compared to other SP triggers of the era. The Nasty trigger was primarilly retailed from Paintballwholesalers (originator of the Nasty Shocker, Nasty Impulse, and Nasty Nerve) but it was also available from some other retailers later. No bearing.

Smart Parts Dynasty trigger Dynasty SFT triggers were similar to a Nerve trigger, but a litlte straighter in shape compared to the Nerve trigger which reaches backward. The Dynasty trigger came on Dynasty SFT Shockers but was also available from many major SP retailers since it was a factory accessory. No bearing.

New Designz wave trigger One of the more popular NDZ triggers; shaped somewhat like a double trigger with very rounded front shape. These triggers were released before bearings became popular, so many do not have bearings. Later the Wave was re-designed to use bearings alongside the NDZ Roller Blade triggers.

New Designz RIP trigger These triggers were seen during a fad movement around 2003-2004 when it became popular to "fan" the trigger with your finger up and down, thereby firing every time your finger hits one of the humps if done correctly. These triggers were released before NDZ started using bearings, then popularity decreased later, so they never included bearings.
New Designz RIP trigger (SFT style)
New Designz blade trigger Another popular NDZ trigger. The "roller blade" was released later compared to the NDZ Wave and RIP triggers; the blade was the first NDZ Shocker trigger to use bearings.

New Designz slik trigger The last trigger NDZ created for Shockers/Nerves. These were released in 2005 using a modified design compared to the previous NDZ triggers (Wave, RIP, and Blade). The NDZ Slik triggers are undoubtly the lightest in weight, and feeature a new front shape that had become very popular at the time. All Slik triggers use bearings for pivoting.
Note: the Slik triggers do not have support for a magnet return, instead they can only use a spring for return. Many players would simply remove the spring and magnet, instead relying on the trigger microswitch for return.

Custom Products roller trigger Popular stick-shaped trigger with a simulated roller microswitch activation. These triggers do not have adjustment for pre-travel, firing point, or magnet tension. The triggers also do not use the standard Shocker/Nerve trigger pin, rather they use a special one-sided bearing that pushes against the side of the inner frame because the trigger is held in place using a small screw and nut. The screw/nut system can be difficult to inststall, and parts are almost impossible to find in the current year.

A-plus delrin triggers These triggers are machined from delrin and include a roller bearing. They were manufactured by A-Plus anodizing in late 2003. Three styles were available, as shown in the picture.

Trigger Removal/Installation:
you may find the need to remove your trigger if large amounts of dirt or debris get clogged between it and the frame. Alternately, trigger removal is required in order to install an aftermarket trigger, obviously. Here are steps to take:
1. Remove the grips and disconnect the wire harness from the lower board. Separate the frame from the body by removing the two frame screws (1/8" allen wrench with most frames), gently set the body aside.
2. Use a metal punch, nail and hammer, or other tool to remove the trigger pin from the frame. This is the small circle located directly above the trigger in the frame.
The trigger will slide down and out from the frame, however you may wish to unscrew a few of the trigger's set screws if they are adjusted too far out. This includes the firing point and/or pre-travel screw. If using a Nerve frame or another frame with the trigger rest plate, remove the plate for easier trigger removal.
3. Once the trigger is out, slide in the new trigger and reinstall the trigger pin. Some triggers require different instructions (such as the CP roller trigger, refer to their instructions if necessary). Adjust the trigger set screws to your preference.
4. Reconnect the frame with the body, while being sure not to pinch the wire harness during reassembly. Reconnect the wire harness and reinstall the two frame screws.

Microswitch Orientation:
Certain triggers are designed to function with different microswitch positions. Please refer to the related links section for a link to the microswitch orientation page in the adjusting and maintaining section.
