Not how it works with " typical handguns @ typical handgun distances "

The two main factors are bbl dwell time , and muzzle rise from recoil .

Slower & heavier spends longer in bbl , giving more milliseconds for muzzle angle to rise from recoil before bullet actually leaves muzzle .

Faster & lighter spends fewer milliseconds in the bbl , and muzzle hasn't moved as far upwards .

That's why when switching from 158gr to 110 gr duty ammo , front sights were filed DOWN .

Now if we were shooting at 100 plus yards . then ballistic coefficients and gravity , etc become important factors.

I know ,counter intuitive if you primarily deal with typical centerfire rifles , but for at least 25yds , up to 50yds , dwell time and muzzle rise are controlling .

My bad- I must have skimmed. I didn't catch that we were speaking of 21 foot shots. You are correct, and a big oops for me. ;-)

I bought my new Max 380 pistol 2 weeks.
I Shot it last weekend. I averaged 13 inches low with 4 brands and gr of ammo AT 7 YARDS OFF a excellent brand of pistol rest. I had 2 guys shoot pistol with same results at range. No way to file the front sight down because of the illuminated type of front sight so has to go back to factory To be honest with you I would prefer a regular ramp site so you can file it down if need be and just paint the front sight every year. Will know in 2 weeks they said if they can fix it. I will report back and hope I can then brag on pistol and their customer service warranty work. Marty

"Pretty sure slower and heavier physically HAS to drop faster. More weight and less momentum- try it with 2 weights by hand."
Physics says that 'in a vacuum, weight does not change the rate of drop' ( in a vacuum, a feather falls at the same rate as a lead slug).
Anyhoo, it's not about the 'drop' of the bullet. It's about the movement of the gun while the bullet is still in the barrel(proven fact BTW). Slower/heavier bullet exits the barrel later in the recoil cycle(and resulting muzzle rise) resulting in a higher POI on target.

Same issues as the OP. Sent back to Ruger, returned with no improvement. Accuracy also generally pretty poor. The complaints about this model are extensive.

Ruger crapped out on this design. Sold it, went back to my old .380s.
