Frame mounts

(14 products)

A frame mount is an under-frame attachment that adds forward weight and gives you a mounting point for accessories such as thumb rests, compensators or Picatinny rails.

Why do shooters use them? To stabilize the gun, manage recoil more effectively and customise the front of the pistol for competition or training.

Will you benefit from added front weight and accessory space?

Most sport and competition shooters do. Extra mass under the dust cover helps the muzzle return flatter between shots, while the accessory area allows you to position a thumb rest exactly where you want it—or add a Picatinny section for lights or further tuning.

Key advantages of a frame mount:

  • Reduced muzzle rise thanks to weight placed forward and low on the pistol.
  • More consistent recoil control during rapid strings and transitions.
  • Accessory flexibility — attach thumb rests, compensator supports, or a short Picatinny rail.
  • Better front-end balance for sport, IPSC/USPSA, steel challenge and precision practice.

How to choose a frame mount

Compatibility with your pistol

The mount must match your exact model and frame geometry. Dust-cover length, screw positions and contour vary across CZ, 1911, SIG, Beretta, Walther and HK platforms.
  • CZ (Shadow 2, TS 2, SP-01, etc.): mounts differ by dust-cover length and recoil-spring plug style. Match the mount to your specific variant.
  • 1911/2011: check government vs. commander length; some designs use existing frame holes while others require a clamp-on style.
  • SIG Sauer P320 / modular frames: fit depends on grip module type (X-Series, Carry, Full-Size); verify hole spacing.
  • Beretta, Walther, HK: confirm generation and dust-cover profile. Some polymer frames may require specific hardware.

Material

Brass

Pros: maximum recoil damping, very stable sight picture, excellent for competition.
Cons: adds significant weight; less suited for daily carry.

Aluminum

Pros: lightweight, strong and widely available; ideal for tuning balance without making the pistol nose-heavy.
Cons: less mass than brass, therefore slightly less recoil reduction.

Accessories you may add to a frame mount

  • Thumb rest: gives stronger support-hand leverage and improves control in dynamic stages.
  • Picatinny rail section: enables mounting a light or additional tuning accessories.
  • Support for compensator systems: some mounts work as stabilizing bases.

Can I install a frame mount myself?

Usually yes. Most mounts bolt directly to existing holes or use a clamp system under the dust cover. Follow the included instructions and use the supplied hardware.
Check screw tightness periodically and ensure the mount does not interfere with the slide, guide rod or holster.
Minor fitting may be needed in rare cases due to tolerance differences — always remove material from the mount, not the pistol.
