ISMI – 16 Pound 1911 Commander Recoil Spring

ISMI 16 lb 1911 Commander Recoil Spring

Consistent Cycling for Commander‑Length 1911 Pistols

First and foremost, the ISMI 16 lb 1911 Commander Recoil Spring keeps your pistol cycling smoothly and reliably. By controlling slide speed more precisely, it promotes clean feeding, proper lockup, and consistent timing. As a result, your Commander‑length 1911 operates predictably shot after shot, whether you use it for duty, daily carry, competition, or range training.

Moreover, this recoil spring performs exceptionally well with both standard and full‑power ammunition. Consequently, it delivers stable performance without excessive slide velocity or unnecessary stress on internal components.

Precision Manufacturing to Aerospace Standards

To ensure repeatable performance, ISMI manufactures every recoil spring in the USA using advanced CAD design and aerospace‑level production methods. Because of this precise engineering, each spring delivers uniform tension and consistent results. Therefore, your 1911 maintains smooth operation and dependable function over extended use.

ISMI Recoil Springs Built for Strength and Reliability

Premium Chrome Silicon Wire Construction

ISMI produces this recoil spring from high‑quality Chrome Silicon wire to maximize strength and service life. In addition, each spring undergoes a multi‑step strengthening process:

• Heat treating increases overall strength

• Shot peening reduces surface stress and fatigue

• Full stress relieving prevents permanent set

Together, these processes stabilize spring tension while reducing wear on the slide and frame. As a result, your pistol cycles smoothly while maintaining long‑term durability.

Why Upgrade to an ISMI 16 lb Recoil Spring?

Over time, factory recoil springs lose tension. When that happens, slide speed becomes inconsistent, feeding reliability suffers, and frame battering increases. Fortunately, ISMI recoil springs solve these problems.

Specifically, the 16 lb spring balances slide control and recoil impulse for Commander‑length pistols. At the same time, it safely manages full‑power ammunition while keeping slide movement smooth and predictable.
