I've got 7 Gov't size all are 45acp . Most are SA , 1 Nork & 1 DW Valor . I imagine the DW is good to go & only 2 mods I'm considering are a small radius FPS & a tighter barrel bushing . The SA's I'll gradually replace all the MIM stuff along with small radius FPS & tighter bushings . Years ago the C&S extractors were the cats meow , but needed some mods etc . These days I'm more inclined to either the EGW HD , Nowlin " Tuff Stuff " or Wilson " Proof " . Looking at the EGW it seems the most robust , but looks as though they might be a pain to fit . Have no personal preference but would prefer something that'll give good service assuming I do my part & fit them correctly . Was wondering what the current consensus was . Bushings I believe I'll go with EGW angle bored as I can get them custom machined to my dimensions . Lets say I want .001" clearance both ID & OD . Do I subtract my clearance from actual measurements or just order what barrel diameter & slide opening actually mic ? I've only fit NM bushings on BE guns & using the EGW's all the works pretty much been done . No reaming , expanding skirt to fit slide or turning down & no relieving for barrel lock / unlock clearance . I've been fitting / installing small radius FPS & really like the Harrison ones . They come with a 3/64" bevel already & are less work to fit than the EGW ones especially if you're doing it all by hand . I'm also looking at their smooth faced triggers with fixed overtravel stops . Dang serrated trigger faces eat my fingers up now days & are painful if I shoot more than 50 rounds .
