I have a glock 21sf Gen 3 for about 7 years now and it has well over 7,000 rounds through it. Recently I have light primer strikes on my reloads and factory loads, so I thought the logical thing to do is get a heavier striker spring. I got a 6lb striker spring and now I have no problems with light strikes but now my reloads and factory reloads have the dreaded FTF (failure to feed) on some rounds and I have to hit the slide forward to feed correctly. So my question is, do I need a new recoil spring due to the heavier striker spring? And does the plunger spring replacement make a difference? Thank you in advance.

If you haven't replaced your recoil spring yet, that's likely the problem. An easy check, with an unloaded gun, pull and trap the trigger to the rear. Point the gun up, so the barrel is vertical. Pull the slide to the rear and the slowly ride it forward, stopping about an inch from it being back in battery. Release the slide. Did the slide return to full battery? If not the recoil spring needs replaced. On a large frame Glock I replace recoil springs every 3000 rounds, after all it's less than $10 and anyone can replace it. -
Thank you for the reply I will definitely look into that. What is the benefit of a heavier than stock recoil spring, if you don't mind me asking?Comment

You don't need a heavier recoil spring, yours is just worn out. Get a OEM part from Glock and you should be good.Comment

Sounds to me like you installed the slide lock spring wrong.NRA Life Member and Certified Instructor: Pistol - Rifle - Shotgun - PPITH - PPOTH - NRA Certified RSO

I would have gone with new standard striker spring and recoil spring. After all, the standard ones worked well for 7000 rounds.Comment

Standard runs fine. (17 lbs.)
Also make sure you clean out the firing pin channel ( in case you didn't already).
After 7000 rounds plenty of black gunk builds up in that tunnel. Remove the firing pin and using a couple of Q Tips clean the channel until it's clean and dry.
No lube at all. None. Did I mention to not lube the firing pin?
