I have 2 also. Very nice. Very little movement at all in pull or reset.
Very fast. Might be good for target too - light pull - but never tried it. It's for fast. Really fast.
I have shot a couple of Geiselle Super 3Guns for many years in my main rifles (223 and 22), which are also very very good, but I think I like the Hiperfires a little better. All else equal, they do have much more robust primer ignition because of those extra springs that drive the hammer without affecting the trigger pull. It's a pretty sweet little system.
Will you be at DPRC either day this weekend?
