G21 10mm 22# spring

[AndyWest]

I put a 22# Wolff spring and rod in my G21 10mm conversion project and encountered FTE's about 1 in 10 (stovepipes) with BVAC 180gr, 100 rounds. All else is stock. I don't mind a break-in period but now I'm thinking 20# would be more appropriate. Thanks for opinions.

I don't have your answer. Here is a link to the 21 to 20
conversion part of a dedicated 10mm forum. There will
be more info over on the Glocktalk forum, also.

A 22lb spring is overkill and will beat a slidelock into early submission.

what was wrong with the factory spring?

Glock 21 is chambered in .45 auto, G20 chambered in 10mm auto; different pressure cartridges producing different recoil/slide velocities...

I use a 20 lb spring in mine---works great

^^ What AZAK said. The factory spring does work, I just don't want to catch a face-fulla-slide some day.

Thanks plouffe and all, lookin forward to my 20#.

[Edit]

10mm4ever: Yeah, it was abusing the slide lock also. I've gotten into the habit of pulling the slide to reload a new mag, but still....

I run a #22 spring in my g20 with hot loads down to sub sonics and have no problems. The 20 came before the 21 and had a heavier slide, when glock built the 21 on the 20 frame they had to lighten the slide to get the weaker 45acp to function. I would stick with the heavier spring to keep the barrel locked up longer and look at your extractor instead.
Just my 2¢…
