Anybody have any trouble with the ruger polymer rails that the slide rides on, most other pistols have steel inserts.. Will this cause it to wear much faster with the polymer rails..thanks

You might want to ask this question over on the Gunsmithing list. But IMO Yes it will wear faster then the steel inserts Question is how much faster will it wear?? Not sure I have a buddy that owns a new P series in 45ACP and if he would clean the thing once in a while it would shot just fine . but I have not noted any wear on the frame as of yet.
