I have posted on here somewhere or other that my old G17 occasionally "light strikes" the primer, so I ordered a new striker spring and recoil spring to eliminate those two possibilities. I got the stuff from Brownell's and the recoil spring looks exactly like the old one, but the striker spring was longer (maybe 3/8 inch?). At the time I was busy cleaning and keeping my mind on how to get the thing back together and in the process forgot to count the number of coils on each spring- so I don't know on that (and I kind of hate to pull it all apart again). It seems to function fine and the coil wire looked identical. I just wondered if maybe the old springs got superseded or if that spring just took a set at that shorter length from being partially compressed for so long. Not real worried about it, but wondered what you guys would say on this.
