hello everyone! i bought my first gun the glock 22 rtf2 in november 2009 without knowing the model was changing to the gen 4 in january 2010 i really like the feel of the rtf2 and i think the fish gills makes it stand out from the rest but im kind of concerned they only made the rtf2 for only 1yr. so what do you think guys? keep my rtf2 or should i switch it out for a gen4? (i can only afford to have one) thanx for your opinion glock fam!
