i have also felt, while playing with viking mp 446 polymer version of 2009 & 2010 that the polymer used in 2009 make seemed to be of inferior quality if compared with the viking mp 446 2010 , as the model 2009 is lighter than 2010 plus the double action trigger of 2010 make is also far better than that of viking 2009 .......... wat about 2011 make ? has it retained the quality of 2010 or improved or even recourse to poor 2009 model, tea pot
