Best Bore Sight for Subcompact Pistols
Finding the right bore sight for a subcompact pistol can be tricky. Many universal bore sights are designed to insert into the muzzle and require enough barrel length to sit securely inside the barrel.
For some subcompact handguns, the shorter barrel simply doesn’t provide enough room for a traditional insert-style boresighter to fit properly.
Why Barrel Length Matters
A universal muzzle-insert bore sight needs enough internal barrel space to stay stable and aligned with the bore.
This usually isn’t a problem with full-size or compact firearms. But with shorter subcompact barrels, fitment can become an issue, even when the caliber itself is compatible.
So what’s the alternative?
A Cartridge-Style Bore Sight
Instead of inserting from the muzzle, the Aeroshot 2-in-1 Dry Fire & Bore Sight Laser is built to the dimensions of a 9mm cartridge and sits directly in the chamber.
It can be inserted manually or fed from the magazine like a cartridge, making barrel length much less of a concern.
In Bore Sight Mode, the laser stays continuously on while you align your optic.
Switch the rear cap and it becomes a Dry Fire Trainer, producing a short laser pulse when the firing pin strikes.
That means one device can be used for both:
- Bore sighting your optic
- Dry fire training at home
The 2-in-1 uses a patent-pending design, combining two useful functions into one cartridge-sized laser system.

Which Bore Sight Should You Choose?
If your firearm has enough barrel length, the AeroShot X03 Universal Laser Bore Sight is a convenient option. Especially if you want one tool for multiple calibers.
But for a short-barrel 9mm subcompact pistol, a cartridge-style bore sight can be a much better solution.
