    What is the difference in lock times between a TM1 with coil springs vs. leaf springs?

    All depends on whether it is a German spring or an Italian spring. HMB

    Depends on which one has the titanium firing pin.

    Does matter really. What matters is which one remains the same consistatly(repeatablity). That would be the leaf. Coil springs degenerate in performatance from the begining of use.

    Leaf springs are job security. They have been obsolete for decades.

    German coil springs do not degenerate. HMB

    Aber es macht einen großen Unterschied.


    Größte Unterschied ist wenn die gewickelten Feder auf einer Stange, die Feder wird noch Funktion wenn gebrochen, vielleicht nicht so gut, Wereas ein Blatt Feder überhaupt nicht funktionieren

    Coil springs are good enough for Kim Rhode.

    Leaf springs are consistent.....until they break.

    Consistent?.....So explain why a truck sags when it gets used? Leaf springs peter out just like any other spring. Spring steel is spring steel....what ever configuration you manufacture it in.... it's still "spring steel".

    A pretty good shooter and confirmed Perazzi guy told me the coil spring triggers now sold by Perazzi have only one drawback as compared to the leaf version, release versions are not available. Who said that? Ray Stafford. I think he would know.

    If you missed, it wasn't the spring

    You were right with "nanoseconds".

    All springs compress over time. They do it under tension as well as through being worked. It's quite obvious if you just take a new spring and hold it up next to a spring that has 10,000 rounds of use.

    Almost every Perazzi flat spring that I've had fail broke or ripped near the perpendicular peg attached near the "hairpin" of the spring. That makes the spring easy to replace but it certainly is a natural weak link in the design.

    About two years ago i decided to try some of Marcello's flat springs with an independent pin that fits ridgidly to the trigger frame. Once the pin is in place the new type springs slide over the pin then you compress them under the hammer cradle the same as usual. There is no separate left and right spring. One spring will fit either side and that's only one advantage of the system.

    Since the pin stays very ridgid there's no "wallowing" where the old style spring's peg fitted in the hole. The spring fits over the permanent pin precisely. I predict that this more precisely engineered and machined system will become the standard, eventually. Further, I think these new springs will last far longer than the old design. This is due to the fact that the new spring has no peg attached to it and then loosely riding in the frame hole where it can bind. Also, the new spring rides freely on the permanent pin further lessening, significantly, stress on both pin and spring.

    Since using these springs none have broken nor have my trigger pulls changed. Nothing scientific but encouraging none-the-less. I think this new spring system is much better than both coil and the old flat springs. More time and rounds will tell us more.

    Somebody might want to tell Ms. Rhode that there is a better way. Perazzi wont like it though, because they don't make 'em.

    A properly designed coil spring will never loose tension or break. If you doubt this, think about how many million cycles a car engine valve spring goes thru. Ever see one break?...SMOKIT
