Steyr LP5 trigger

Hi Folks

I hope you'll indulge me for a moment. I'm not really clear on the terminology, so any corrections are welcome.

A couple of questions about the LP5 trigger:

1. Is the trigger, in fact, 2 stage? To me there's a certain "take up" or free play initially and then you encounter "the trigger". Is this free play the "first stage"?

2. Can the trigger be adjusted from "crisp" to "roll"? If so, is it just a matter of adjusting the "over travel" (meaning the movement after the shot is released)?

Thanks.

LP5 is a single stage, you have a crisp one? Most consider it a roll trigger, you might just need to take out some of the travel.

Thanks for the reply, Richard.

Put another way, my second question is this: is the difference between a crisp trigger and a roll trigger just a matter of how much over-travel there is?

People play with settings to give them what they feel is a roll "type" trigger, but its really more in the shape of the sear mating surfaces. The roll trigger gives you a perception of a gentle rise in trigger force and almost a drop off in force before the trigger break. The easiest visualization I can think of is running our hand over a tennis ball and just as you get to the top the trigger breaks.

After travel is a different story really, you can have crisp and roll triggers with or without after travel. Some people prefer no after travel and some like after travel. Personally I like after some after travel, that way as I continue to put pressure on the trigger, when the shot breaks, the force is released, the trigger doesn't smack against a hard stop. With Morini electronic triggers I don't think it's as important as the trigger force is done with sprigs so the force is constant even after the shoot release.

For the record I shoot an LP10 and I also have an LP5 that doesn't get very much trigger time (more of a back-up).

Yes. A good visualization.
