Description
The LaserLyte Laser Cartridge for 45 ACP packs two jobs into one machined brass cartridge. Drop it into the chamber of your .45, pick the end cap for what you're working on, and you've got a bore sighter and a dry fire trainer rolled together. It aligns to the bore and doesn't poke out past the muzzle, so it plays nice with just about any barrel length.
What the Two Caps on the 45 ACP Laser Cartridge Do
The bore sight cap stays constant ON, throwing a steady red dot downrange so you can line up iron sights, red dots, scopes, or a laser without burning a single round. Swap in the trainer cap and it switches to firing-pin activated. Every time your hammer or striker drops, you get a quick red flash, roughly a tenth of a second, showing exactly where that shot would have landed. That instant feedback is what separates this from plain dry firing, and it's where a lot of folks see their trigger control and sight picture tighten up fast.
Dry Fire Training at Home With the LaserLyte Cartridge
Pair the trainer cap with any of LaserLyte's electronic reaction targets and you've got a full practice setup in your living room or garage. It's a favorite for working concealed carry draws, holster presentations, and repetition drills where getting to the range every night just isn't realistic. Because it runs on included batteries and reads like your own pistol handling, you're training with the gun you actually carry.
A couple of real-world tips worth knowing: keep the chamber and bore clean for the most consistent dot, and if the laser ever looks slightly off, pull the cartridge, rotate it a bit, and reseat it. Keeping the O-rings lightly lubed helps with both accuracy and ring life. Treat it right and it'll log a lot of reps before the battery ever asks for attention.

Frequently Asked Questions
How is the bore sight cap different from the trainer cap on the 45 ACP laser cartridge?
The bore sight cap stays constant ON, projecting a steady red dot so you can align iron sights, red dots, scopes, or a laser. The trainer cap is firing-pin activated and only flashes for about a tenth of a second each time the hammer or striker drops, showing where that shot would have hit. You just swap the caps depending on whether you're sighting in or running dry fire drills.
Can I use this LaserLyte cartridge with LaserLyte electronic targets?
Yes. The firing-pin-activated trainer cap is designed to work with all LaserLyte electronic reaction targets, which makes it great for scored dry fire drills at home. The bright red flash is what the targets pick up on each trigger press.
Does the cartridge fit any .45 ACP pistol and will it stick out of the barrel?
It drops into the chamber of standard .45 ACP firearms, aligns to the bore, and does not protrude past the muzzle, so barrel length isn't an issue. Just make sure your firearm is completely unloaded before chambering it. For the most consistent dot, keep your chamber and bore clean.
If the laser dot looks a little off, what should I do?
A quick fix is to pull the cartridge out, rotate it slightly, and reseat it in the chamber, which often cleans up the alignment. Keeping the O-rings lightly lubricated also helps with both accuracy and the life of the rings. A clean chamber and bore go a long way toward a repeatable dot.
