Read the instruction over and see if you want to tackle it, you may need to buy some tools, which can be expensive if you don't already have em. Raynor's instructions are the simplest, but Perklo's instructions are very detailed as far as disassembly and reassembly. You only need to remove the bottom 3 pins. I didn't build the jig for knocking the pins out, just put masking tape over the pins so you won't mar the frame it the punch slips off the pin. A wood dowel of the correct size will work for the slave pin, also. You can easlily get a <2½lb, crisp, glass smooth trigger with no creep with very little honing.
