My G30 RSA has a dark inner sleeve and the ones in my G26 and G27 are indeed shiny. However the forms are the same; that's how I interpreted the question: old style single spring vs. new style dual spring.I don't recall my old one having the shiny metal piece..Found a picture of the old one..
I don't recall my old one having the shiny metal piece.
Could the old spring be the reason my g30 fired out of battery causing frame damage ?
Chamber support on my g30...
You mean lack of.. Hard to tell from the angle, but It appears to have no support past the webbing, hence the blown out case in the above picture. It's not the first glock to do this nor will it be the last. I would pick up another barrel (KKM) or see if glock will replace it with one that has more support.
I replaced my G30 recoil spring assembly recently, and the new ones do look like the one you have. The older ones were different.Not to long ago my g30 suffered a cracked frame due to a KB. Glock replaced my g30 frame and recoil spring. I don"t remember my original recoil spring looking this ... Anyone has one of these ?
