    At one of the GSSF matches right after the introduction of the gen 4's I recall the armorer saying that there was a difference in how the 4's are assembled. I think he was talking about the trigger mech housing and trigger spring orientation. What should I know about assembly or disassembly of a Gen 4? Are there any other differences? Besides the mainspring assembly/slide, magazine release and the difference in the grips, are there any other unique parts to the gen 4's?

    Strictly speaking of assembly and disassembly, they are IDENTICAL.

    Unique parts:
    1. Gen4 - A more scalloped trigger housing to cater to the new smaller grip.
    2. Gen4 - Trigger bar has a dimple where it meets the firing safety plunger. This adds to the weight of the trigger pull.
    3. Gen4 - The obvious muzzle end of the slide has a bigger recessed/beveled hole for the dual recoil spring to sit.
    4. Gen4 - Barrels I believe have a bigger recess near the chamber for the dual recoil to sit in.
    5. Gen4 - Newer manufacturered version come with the dot connector to help with the trigger pull.

    Other than those minor things they are identical.

    My G23 Gen 4 seemed to be identical to a Gen 3, I put a - connector and 6lb spring in it. The Gen 3 parts worked just fine. The only difference I noticed was that the Gen 4 trigger bar has a bump on the side of the portion pressing up on the firing pin safety, but I replaced it with a Gen 3 smooth trigger.

    For a while when the Gen4's were first released, some Gen3's and Gen4's required either setting the trigger bar forward and/or depressing the firing pin safety with the muzzle of the slide pointed to the ground.

    :dunno:
