Glock 17 Gen 4 Parts Kit

[klepper62]

Any suggestions for some spare parts I should pick up for my Glock 17 Gen 4?
No issues to date but I would like to be prepared for a possible future breakdown.
Thanks

firing pin, all springs, extractor, springs.

if you want to be sure, another barrel and ideally a spare gun

2 is 1, 1 is none, and if you have none, you are done.
