View Full Version : Glock 19 recoil springs (black or grey), and solid rod questions

I have a gen2 G19 that is running a black recoil spring (17# ). The replacement recoil assm. uses a grey (18#) spring. What is the theory behind tuning recoil springs-- why a lighter or heavier spring?

Is it good to replace the factory plastic rod with a solid SS rod for a CCW?

Its easy to tune the recoil spring to match the ammunition performance. If your ejected brass is flying out there 10 feet or so you should increase the recoil spring weight. If your brass is rolling off your knuckles you should decrease the spring weight. Ideally your looking for the ejected brass to land in a small group about 4 feet away.

The early Glock pistols had a problem with the plastic guide rods chipping, cracking, wearing or flat out breaking. Current issue plastic guide rods seem to last much longer and are not as prone to earlier problems. Stainless guide rods seem to fill the nitch for anybody that is concerned about early issues with plastic guide rods.

Thanks for the fast reply.

Personally, I really don't care how far the bass goes, as long as it clears the slide.

What's more reliable in spring pressure-- lighter, correct?
Lighter recoil spring also means "harder" slide recoil, maybe?

For competition- they use heavier springs for more recoil dampening??

Lighter is not necessarily more reliable.
The lighter you go the harder the slide hits (unless you shoot lighter ammo)
