These guns are tools. Each designed/ brought to life to do a job. Fortunately Parker could and would make what you want.
An upland hunter wants a lite gun to carry, a duck hunter a heavy gun, a pigeon shooter, trap shooter etc all different.
IMO, based upon some reading and history, the game of skeet is what kept the 28 ga alive and help bring its exposure to more shooters/ hunters via sales man etc.
Again the value of a gun is in the eye of the beholder. We all want something different. Just like Mr Corona said we each have different tastes.
If any one out there has a 34" 28 ga on a O or 1 or any frame size and is not happy with it, please give me a call.
