I have an older 2nd gen bought in Jan 2005, and a new 2nd gen bought this past weekend. My question is this; Can my older pistol be "upgraded" to the same level as my new pistol? I know my newer pistol has several improvements like the new extractor and hammer block, etc. Can these parts just be dropped in? How much work would need to be done (like on the ramp) to the older pistol if it is possible? I am no gunsmith and if I can't take it to Kel Tec (I live about an hour and a half away) or send it to Goldenloki or someone else with more experience then I probably wouldn't be comfortable doing it. Thanks in advance for all your help and please excuse any "noobness" or whatever on my part.
