the EAA is an aluminum frame right? it looks like it, but yeah an all metal gun will definitely help with recoil and durability better than a composite frame. 10mm is supposedly a caliber that's hard on a lot of guns. I've been wanting to shoot a 10mm for a while, you don't really see many of them around though. my .40 S&W barely kicks for its caliber size and my 9mm carry piece starts to dig into my hand after 50 rounds. I gotta get me a big caliber, all metal "fun" gun soon, I was going to get a kimber stainless II with my tax check but I got a tv instead
