I wonder if we will look back on the 805 like some people do to the all metal frame pistols. The S&W 5906, CZ 75 and Sig 226 could be considered the pinnacle of semi auto handgun design. Although heavier than their stryker fired, massed produced, polymer equivalents, there is no substitute for their solid feel and robust build quality.
For the duty pistol, by all means take the polymer pistols. For the gun collection and range shooting, my preference is the sturdy steel frames. It will be interesting to see how the 805 vs the Bren 2 will settle out over time.
