I measured my original TM spring to be 9mm, and the Element one to be 10mm.

Try a king arms one from illusion, I've had success with those, I think I bought his last 2 though :D

You jerk! Always ruining everything for everyone ;)

I'll sell you one for $30 muahahahha

Thats gouging!!

I've used Guarder spring in all my 1911/2011 build(minus the open gun, it uses Airsoft surgeon, bought it as a test part)....none have any issue....SD slide(plug), AS plug, stock 1911 plug, Nova plug, 9Ball plug....etc

I've never had any problems with Guarder springs, either...

Weird. Because when I got it, it wouldn't compress at all into the spring plug. I mean it would go in, but when it was coiled up, it would not fit into the spring plug.

I've had problems with half the Shooters Design spring guide bushings... basically, the interior was extremely rough and/or not reamed out to the proper inner diameter. Attacking it with a cylindrical file helped alleviate the issue.

^ Same issue....Very odd that the SD does everything else so well, but their guide bushing/plug is so shoddy....

Yeah I've been doing this. It is much much better than it was originally. I'm going to keep going at it I guess until it works perfectly.

Guarder springs worked fine with mine. AS springs are fine too.

Thanks for the info guys :)
I have another question regarding the KJW Hi Capa.....what rail would fit on it? I'm looking at putting a red dot on it....
Thanks gain.

Talk to illusion about that. =)

I just got a KJW 6" Hi-Capa, guarder 150% spring fit just nice. The spring fit perfectly on WE 5.1" Hi-capa as well.
