the slidelock spring on my G23 popped yesterday. so far, the gun is completely stock. i figure since i will have to buy a new spring and i was planning on detail stripping the gun for cleaning anyway, now is the time to order parts! but i am new to this and don't know what to get. what other springs should i keep on hand? i've heard a 3.5 lb connector makes the trigger pull smoother. is there anything else i need to order with this? why is it $25 when the others are only $4??? i'd like to upgrade to a metal recoil rod. what's up with different types (like tungsten)? do i really need that fancy "glock disassembly tool" to detail strip my gun? anything else?? thanks for helping a newbie out!
