Precision ground from solid durable tungsten. These allow you to use common 1911 springs in your Sig Sauer X5/X5 Legion. This allows you to easily tune your gun to your loads and preferred recoil impulse, while getting the added weight of tungsten. Works with the ISMI X5 recoil springs we offer, which provide better lock up over 1911 length springs.

Weighs 3.4oz.

*ONLY compatible with the X5/X5 Legion, MAX, XTEN, DH3.*
