Ok, let's assume shooting technique is perfect and ammo is a nonissue.
Now as I have mentioned before, my four R9s shoot fine without isssues. I bought the first one new in 2006, the rest used in 2010, 2011, and 2012. i thought the serial numbers were all over the map and told a forum member so. However, upon closer inspection I found that they ALL fell in between the range of 1200- 2000. Wow, what are the odds?
So now I am wondering if maybe the earlier guns had more time and attention paid to them. Or maybe the springs were better?
Or as time wore on and as the R9 gained popularity, maybe the factory did not have as much time to polish this or that as much. Or radius this part as much as it should or tweak that spring juussst right, like they used to.
The desire is there, just not the time.
So, as a little nonscientific test, you problematic guys, give us your serial number range, e.g., 12xx. You flawless feeders, please do the same.
It is just so puzzleling to keep reading about all of these problems, when a lot of us just don't experience it.
What you say? Give it a whirl?
