  • 1x Align Tactical THUMB REST Takedown Lever for Sig P320


A thumb rest is something most shooters associate only with a competitive handgun; however, the Align Tactical THUMB REST Takedown Lever allows you to have an ergonomics thumb rest on your standard Sig P320 as well.

As the name suggests, this takedown lever has an extended ergonomic ledge, which you can use to rest your thumb while shooting. This allows you to control the pistol more effectively and counter muzzle rise. As a result, it helps you shoot faster and more accurately while decreasing the chances of your support hand slipping from the pistol as you shoot.

The ledge also has textured serrations to help you apply effective resistance. The profile of this thumb rest is quite minimalistic. It has rounded edges to prevent snagging and only comes out about half a thumb's width.

The Align Tactical THUMB REST Takedown Lever for Sig P320 is also approved for use in USPSA Competitions and can greatly improve your shooting ability.
