Did a search and have been reading up on the 910, from the forum here.

Has anyone replaced the Magazine release with a metal replacement?
Saw a lot of post concerning this but not any specifically about what parts from what model the used to replace the standard plastic part that comes on the 910. I would think that the 915 mag release button would work, but maybe that's not the case? Please advise.

I will most likely replace the guide rod with the metal one, and order some fresh recoil springs. Looking forward to shooting it next weekend after the wait period is up.

Thanks to everyone for being so helpful!
