Average Weight. 9lbs or more. Barrels were heavier. No adjustable weights. Price, original runs were about $6800 New street price. Then they came out with the Black version to cut weight even more with the use of carbon fiber parts.
The 2nd generation addressed some ejector issues and they changed the barrel makeup (lighter) than the first gen but I don’t know of anything that was “made different” in terms of the receiver or trigger assembly.
