With the Max31 on semi I can easily hit a 2/3IPSC at 160 yards offhand. Didn't try the 180 yard. With the OEM 45 upper it is barely qualified to be an area effect at 180 yards let alone hit the 2/3 IPSC steel.
You're definitely a better shot than me. You're hitting a 20" tall target where that 115gr 9mm bullet has dropped about 15" by the time it gets to that distance, offhand. I definitely couldn't do that with how bad this trigger is. When I last pulled it slowly, it felt like a 15-20 pound trigger.
