    any advice on a trigger that fires about once every 1000 rounds or so by just touching the trigger. Whatever the problem is it happens on both sets of triggers, I make sure to break the gun completly open all the time but it still happens. Can somthing be worn out to stop the sears from getting fully engaged?
    When the triggers are working properly lower barrel is 3.5 lb and upper is 3 lb pull.

    My trigger got really light after about 6 years of shooting. It finally started to make me flinch because it was so light. I fixed it by getting a precision gold trigger.

    Do you have 2 complete trigger assemblies each with 2 hammers ? Yeah the sears can get worn to a dangerous level and need the services of a good gunsmith to tune the trigger. I recommend Phil Crenwelge. I had a problem with my double release trigger with the sears Not disconnecting and I cured that problem by spraying the barrel selector tree and inertia block with solvent to get rid of some grit.

    If it is happening w/ two different trigger groups it may well be that the hammers are not being cocked far enough to fully engage the sears. Take the stock off and eyeball it.
    I have several Perazzis w/ tens of thousands of rounds thru them and the sears do not wear. I admit that I do lube them tho.

    hi colt 1911, you might start by replacing the sear springs. sometimes people cut these springs or they just simply wear out.

    with the trigger assy in the fired position lift up on the back of the sear, then replace the sear spring and see if there is more tension on the sear. if the springs are bad you might get erratic sear to hammer engagement when you cock the gun. (open the gun)

    there should be a sear spring plunger and a spacer on the pin that keeps the sear spring and sear spring plunger in place. many time these parts have been lost over the years. if you hae any questions call (573)286-9905 jd28hd@aol.com doug hubbart gunsmith

    If two trigger groups are doing the same thing, I'd check how it cock the hammer without the stock. The right cocking foot might be short.

    Not likely the sear will fail within 100000 rounds. But check the sear spring as well.

    I think Steve W. is on the money. Check the cocking on the lower hammer. They should over-cock past the sear a couple of degrees and then slide back to engage the sears.

    However, I also would have Phil Crenwelge take a look too!. 210-313-5988

    Any back and forth play in the trigger assy itself can creat havoc also! I had Phil fix mine at the Grand as it was doubling on me! Hap

    About 50% of the Perazzi triggers I get in have the sear spring plungers missing and/or the sear sleeves.

    Not sure why, but it they weren't needed, Perazzi would not make them for their triggers.

    Your "tree" could be worn, the rear sear surface could be worn, and/or the front of the sear or the hammer notch could be worn as well.

    WW - boy, is that ever true!! Prolly way more than 50% too. Out of the 14 Perazzis and several extra trigger groups that have been thru my hands only ONE still had the spring plungers in it.

    The downside of Perazzis being so easy to repair is that every clot thinks they can do it. And they are way more easier to take apart than put together for those folks - easier if you just leave out a few of those pesky little bits.

    For the less than educated crowd, could someone please post a picture with an arrow to the sear spring plunger? Now you got me worried to check my triggers.

    If you don't have the true sized schematic like the one I posted above, then go to my website and download the original sized Perazzi schematic.

    The download here reduced my image.

    I wouldn't be working on these without a good schematic.
