First thing in any 1911 or 2011 I do is replace the Recoil Spring and Guide Rod assembly. I prefer a Flatwire setup as that’s going to offer longevity. The other issue among 1911s and 2011s is that with most manufacturers, they’re not properly sprung. For these Pistols as an overall Platform, there’s only two Manufacturers in thr aftermarket I go with. Wilson Combat and of course, Evolution Gun Works. I get my parts from them knowing that they just work. I’m skilled in gunsmithing as a longtime hobby, so hand fitting isn’t an issue for me. The end result with this product in particular makes the Prodigy look better and function flawlessly. Definitely recommend this Guide Rod Kit from EGW for your 4.25” Prodigy. Combined with the other things I’ve done to mine, it runs fast like a Ferrari and is as reliable as an old Toyota Pickup that just doesn’t quit. Definitely going EGW for specific parts for my next Prodigy that’s coming in another month.
