There is no be all, end all in gas operated semi's. Then add in hi-volume with crappy shells? Sheesh.
If you need to shoot 3.5's and 1oz target loads in the same gun, you are out of luck. Better to get 2, a target gun with light springs, and large gas ports, and a goose gun with small ports and heavy springs in the same model.
The gun co's should just quit the light load nonsense altogether, they just keep digging the hole deeper.
There are a lot of good semi's out there now, but when they try to do too much with the same gun, it just makes guns available on the secondary market. And disgruntled former customers.


Out there doing it best I can.
