First:
If you have not done so already, use the "Build My Kit" tool. There are specific questions that offer a resetting trigger that will answer your question faster than reading this.
Second:
Regular dry-fire practice with most firearms means resetting your firearm for every shot. Introducing LASR to this is very beneficial with the added feedback and functionality.
If you really feel you want a resetting trigger, there are options:
We recommend you get a SIRT Pistol, or, for an AR-15, a SIRT AR Bolt. Both of those are great training aides and offer an auto-resetting trigger.
Of course, if you have a revolver, you could also get a Laser Ammo Revolver Pro Pack.
If you have a manual action, such as a pump or bolt action, then the Laser Ammo inserts and adapters will do nicely and be functionally correct.
If you have a resetting trigger of some sort in your firearm already, such as a double action or double-strike capability, these will usually provide a resetting trigger (although not perfect for DA/SA weapons) when used with the Laser Ammo inserts. Please note that it is your responsibility to understand how your firearm functions.
There are also the Aimtech resetting trigger magazine kits, but only for certain pistols, and they are a final-sale option as the manufacturer is no longer around to provide support.
There are no other options that we know of, that can be taken seriously, but we'll keep our ear to the ground.
