Jon, according to an article by Wakeman, he anticipated the sales of the 28 gauge to begin in March 2009. The introduction was announced by the Upper Sandusky folks at the 2009 SHOT Show. I don't know if they met the March date, but I bought mine in January of 2011. Some of the earlier 28 gauges had to be sent back (including mine) as they suffered "timing" issues regarding ejection. At the time, there was one employee responsible for the 28 gauges and correction of the problem was relatively painless as shipping was paid both ways by Ithaca. Here's the Wakeman article.
