Weird I know. I'm attempting to make all the springs in a Glock pistol at home. Could someone please measure their (non flatwire spring) uncompressed recoil spring. If you could please provide: wire diameter, spacing in between turns (offset), and length of the uncompressed spring. Thank you in advance. NOT DPM SPRING.

EDIT: Thank you to those who are at least addressing my problem. The rest of you, I had no idea this community have this amount of toxicity. Anyways in order to measure spring you will need calipers. (for those of you who are unfamiliar with assembly of glocks) In measuring any part of your glock pistol will not damage it. That is just a fear that unexperienced Glock owners have with their gun. There is no need to destroy your spring. Just use the calipers to measure the diameter of the wire, length can probably be done with a ruler. Diameter of the spring itself is also done with calipers.

I know nothing about tinkering with the innards of guns, but wouldn't the type of steel have to be the same as well? Seems as though just having the same dimensions wouldn't necessarily produce a spring of the same strength or springiness. Or am I way off base?

(I have stayed at a Holiday Inn Express and I was married to an engineer, though!)


Welcome to GT, btw!
You'll probably get much better answers than mine. Good luck with the springs.

Not really. I;m familiar with the heat treatment process so springiness is not a problem.

Which generation? Gen 1-3 use a single spring assembly (all of which are flat wire….). Gen 4 and 5 use dual recoil spring assemblies.

Also, the G17 and G19 use different length spring assemblies.

You need to buy a new recoil spring assembly and cut it apart, yourself. Used springs are going to be shorter than a new ones that were only compressed to be put in the assembly.

It’s kind of a dick move to ask people to destroy their parts so you can get measurements. That is my opinion, anyway.

You do realize the recoil spring is compressed and will need to come apart, and whatever dimension you receive otherwise will not be accurate, do you? You being the uber leet Glockster of the board here to school the noobs, I would imagine you already thought of that. Especially when you are trying to get us to measure parts with a ruler. :rolleyes:

Yet…..you never answered which generation or size.


Is “unexperienced“ anything like inexperienced?

Alright, here you go. If this isn’t helpful, go play in traffic.

G17.4 Interior Spring
962463


G17.4 Exterior Spring
962464


G19.4 Interior Spring
962465


G19.4 Exterior Spring
962466


G17.3
962467


G19.3
962468


And guess what?!? That’s all useless information, since they are all compressed, in the assembly. For measurements to be taken, uncompressed, you have to break the assembly apart. Like I and others already told you. All GLOCK recoil springs, for Gen1-3 are flat. It’s not toxicity or an unwillingness to help. It’s you‘re ignorant and don’t like the answers. One person here is the problem, you. I’m sure you would have had a Hell of a following, if you had approached this differently.

By the way, thanks, for the “caliper” recommendation. I was able to find a set with my firearms tools!

My buddy made a G19 from scratch, or figured out the correct spring values. Being an engineer helps I suppose, however I went to the range with him and it works flawlessly. He took the gun apart and showed me what is involved and I was surprised how basic it really was. I wouldnt mess with it but if you know, you know!!

For $6, just buy a couple rsa. You’ll get at least 10k out of one, more than most people shoot in the life of their pistol.
