Model 1911 Variations Part 3
The shape of the past, present and future
By Dennis Adler
With all four guns using the same self-contained CO2 BB magazine design and similarly based blowback action firing systems, one might expect that all four will have approximately the same average velocity and accuracy with their respective 5-inch smoothbore barrels. Allowing a + or – 5 fps for average velocity between guns, they should all be around 300 to 310 fps. Where I expect to see some difference is in accuracy at 21 feet due to varying internal tolerances, sight and barrel regulation (which too few blowback action CO2 pistols have), and, of course, different triggers. They are all hammer-fired designs but even there, hammer design can have an influence. This will be a proof of the sum total of parts used for each gun. The price spread for all four guns is from a low of $99.95 for the Sig Sauer to $109.99 for the Colt Commander and Swiss Arms TRS, and a high of $119.99 for the John Wayne (the higher price is reflected in the John Wayne name, licensing rights and use of the trademark signature).
