Lone Wolf Distributors is proud to announce our own .40S&W / .357SIG Loaded Chamber Indicator Extractor. We built it to exceed the Glock factory part in fit, finish and safety (compared to non-LCI extractors). With this new style Loaded Chamber Indicator you can quickly verify whether your pistol is loaded or not at a glance.  

The factory Glock part is very hard to identify as a .40S&W / .357SIG part unless you can measure it against a spec sheet. The improved LWD part has an easy to verify "4" stamped into it so you always know which extractor is for your .40/.357

Lone Wolf extractors are investment cast from A1 tool steel.

Must use new style spring loaded bearing with this extractor. GLO-3439. Part number 3 on the Glock Schematic.


  • Loaded Chamber Indicator
  • Flawless functionality
  • Improved reliability
  • Identification - 1 dot on the extractor

    I built me a g23 and G27L. I had extremely difficulty finding reasonable priced parts for this .40 cal model I was having a lot of feeding issues firing pin tips snap etc. Once I put all the lone wolf upper in I went to have zero issues. If you looking for well design quality parts lone wolf is the way to go.
