For some shooters the LOP, DAC, DAH, Barrel length, etc. are considerations when getting a gun fitted or buying a new one.
Iam ainstinct shooter, so having everything exact does not matter to me. However, a gun that fits and feels good is a must.
(Example) It is hard for me to shoot a youth model. The LOP is way too short.A trap gun would be hard to shoot crossing or incoming targets, your head is up too far.
Other than that if you keep your head down and keep swinging you should be succesful with any gun as long as you have confidence in the gun and your shooting ability.
