SIG Sauer P365 magazine loading aid
Load your P365 magazine with less thumb strain.
The right Super Thumb model gives you extra leverage when a compatible compact magazine's spring makes the last few rounds harder to press down — so you can load faster with less strain on your thumb.

Super Thumb for the P365
Product Photo Pending Model Confirmation
We don't yet have a confirmed Super Thumb model — and therefore no product photo — to show for the P365. This space will be updated once fit is verified.
Simple To Use
Three simple moves. Less pressure on your thumb.
Place
Slide the confirmed Super Thumb model over the top of the compatible magazine.
Press
Push down on the follower or top round to create space.
Load
Insert the next round, release, and repeat.
Safety note: Always follow firearm and ammunition safety practices. Confirm the firearm is unloaded and kept separate while working with the magazine, as appropriate for the demonstration and environment.

What the Super Thumb Is — and Isn't
Super Thumb is a compact magazine-loading aid, not a bulk ammunition loader. It helps press the follower or top cartridge downward so the next cartridge can be inserted more comfortably. P365 variants and magazine configurations may differ, so compatibility should be confirmed before ordering.
Common Questions
Frequently Asked
Which Super Thumb fits the SIG Sauer P365?
We’re still confirming the exact Super Thumb model for the P365 lineup. Use the Model Finder or contact ADCO Arms directly to confirm the right loader before ordering.
Does it fit every P365 variant?
Not necessarily. P365 variants can use different magazine dimensions, so this must be confirmed with ADCO on a case-by-case basis.
Does it fit P365 XL or P365 XMacro magazines?
This has not been confirmed yet. Contact ADCO Arms to check your specific magazine before ordering.
Does it fit extended or aftermarket magazines?
Aftermarket and extended magazines can change dimensions and fit. Confirm your exact configuration with ADCO before ordering.
Does it automatically load the entire magazine?
No. Super Thumb is a magazine-loading aid, not an automatic or bulk loader. It helps press the follower or top cartridge downward so the next round can be inserted more comfortably — you still load one round at a time.
Can it help with a new or stiff magazine?
Many shooters reach for a Super Thumb because a magazine’s spring makes the last few rounds harder to press down. It provides extra leverage during loading — confirm the right model for your P365 with ADCO.
What if I am unsure whether my magazine fits?
Contact ADCO Arms directly or use the Model Finder. We’ll help confirm the right Super Thumb for your exact P365 configuration before you order.
What warranty applies?
Every Super Thumb loader carries a lifetime warranty against defects in materials and workmanship.
