Product Info for Wilson Combat Compact Reduced Power Hammer Spring

Recommended Use: Compact / Officer's Frame 1911s in 9mm / .38 Super or .45 ACP shooting light target loads. Not recommended for use with hard primers such as Fiocchi or Magtech; CAUTION: The mainspring and other springs are under tension and eye protection should be worn for disassembly. We highly recommend our video #396 which demonstrates the proper procedure for replacement of springs. Failure to follow proper procedure could lead to bodily injury or damage to your firearm; This reduced power mainspring/hammer spring is a must for Officers/Compact pistols chambered in 9mm caliber. The lighter weight spring reduces cocking pressure and enhances cycling of your 9mm Compact/Officers pistol. These enhanced, chrome silicon steel springs resist taking a set even after thousands of compression cycles for improved performance and reliability over standard music wire springs. They are the top choice of competition shooters seeking the longest in spring life.;image
