One thing I'd like to add about Springfield, except for the Pro I've owned or own every model they've offered! The only negative about Springer, of which I didn't know was a thing until joining ADDICTS was, the parts matching up slide to frame in the rear. Can't say positively all, but all but the TRP line didn't match up looking thru older pics where somehow I had the rear of the slide available. Every Springfield I've had ran perfectly and never disappointed I safely say to anyone starting out there's no better place than Springfield. The RO was just a name put on for that time and yes it's been a success,,,,,,next!
