    I just got a springfield 1911 and after talking to a friend of mine who siad he was lighting the main spring weight of his TRP Operator got me thinking of the benifits of doing so. I couldn't really think of any right off the top of my head. I know a lot of you have been shooting 1911s a lot longer then me so maybe you guys can help me out. thanks

    A lighter mainspring means a little lighter trigger break...but what some people don't realize is that the mainspring is part of the recoil system as well as powering the hammer...it helps slow the slide during recoil. Kimber uses 21 lb mainsprings but the normal weight is 23 lbs ... I've heard you could go down as far as 19lbs but probably only for light loaded ammo....

    Leave it alone . Will make very little difference on a factory trigger . Also as stated is part of the recoil system . Never under stood people spend years getting a college degree and designing a system. So kitchen table gunsmith can change things. Why don't factory hire the table smiths at a lot lower salery . They have the answers.:D:rolleyes:

    Actually a 19lbs mainspring is pretty common.
    I have used as low as 17lbs in USPSA guns.

    It might make your trigger feel a tiny bit lighter and it won't hurt your gun.

    Years and years of use by ISPC shooters and big time custom gunsmiths have proven there is nothing wrong with using a 19lbs. Its a pretty standard part of a 1911 trigger job.
