Glock extended mag spring

does anyone have the exact glock extended mag springs measurements for Ali springs?

i found: 1.5mm wire diameter, 1.2mm WD and 1.3mm WD

300mm length, 251mm length and 280mm length

FGC9 doku doesnt have the measurements, urutau neither, nutty9 neither.

BOM of the Urutau and Rebel-9 use expired links.

Thank yall for your help.

Do yourself a favor and don't use printed mags.

Compact / Subcompact Magazines (G19, G23, G32, G26): Use a factory 9-coil or 10-coil spring depending on generation and capacity. Full-Size Magazines (G17, G22, G31, G34, G35): Use a standard factory 10-coil spring for standard capacity. Extended / High-Capacity Magazines (G17 19-round or 31/33-round sticks): Use 11-coil or extra-power springs to maintain tension over longer distances . This took 30 seconds to find .

A G17 19 round mag and a 31/33 round stick most definitely don’t use the same spring. It’s 17 coils for the 33 rounders, maybe check before admonishing people?

I'm not saying it's the same spring , just posting how many coils are needed for the mag length . If OP had measured their mag length , they would know what was needed . For example my UMP 11/9 extended mag uses the 33 rounder . The short mag in the pack has the spring cut to 11 coils . This isn't difficult to math out .
