Ok, I have heard of that before.
No need to mess with magazines. How is the recoil of the 930? Can lighter loads or shorter hulls be used for smaller defenders?
I ran several hundred rounds of “cheapy” low-base #6.5 Estate target/dove loads and full-on 00-buck hi-base loads through the above specimen before I entered it into the PDW/HD roation. I ran them separately, intermixed, etc without a single malfunction.
I’m not recoil sensitive, but the recoil impulse is MUCH lighter than a pump-gun, and I didn’t feel any real difference between light and heavy loads during all that.
