Glock 34 spring advise pls

[Glocker]

Have a 34 I put a lighter spring (13lb) in to cycle the 147's and 124's. Can I leave it in for all loads, like fac. 115's or do I need to change it out?
Thanks

You'll be unnecessarily beating the gun up with factory spec ammo, plus you'll have more front sight upset. I'd just throw the factory 17# back in it if you want to run factory 115's.

Ditto. Unless you run some seriously under-powered 147/124 grain loads, the stock weight should be fine with them as well. Basically, with full-power 115s you'll have a choice- replace the spring now or replace the locking block and maybe the frame later.

Since it sounds like you're using it for competition (assumption), you should run the 13lb.
