Nothing wrong with polished and blued steel; nor stainless steel, nor aluminum. I enjoy them all, myself. Tend to like old school styling, as well.
Here, just a small trio of pump guns, all of them capable. The Persuader has seen the lion's share of use. Awesome gun. Drop dead reliable.
590, old school-style, is a sweet one too.
Steel vs aluminum receiver is of virtually no consequence to me. Same with my semi-auto shotguns.
Parkerized is quite effective, but polished & blued has 'panache'.
Stainless, anyone? It's all good!
Nickel-plated aluminum receiver? Sweet, too. Browning Maxus Golden Clays.
Let's not forget the tactical self-loaders! Versamax Tactical and Beretta 1301 Tactical:
Shotguns are just sa-weet!
