Looks like a decent pistol,,I have to admit I've never looked one over. I just don't follow the newer stuff.
My 2 1911s are mid 60's stock 1911A1 pistols.I just like them that way. No frills or add ons. This Remington looks pretty close to that.
As to the investment cast vs the forged piece,,,given a quality investment casting and then followed up with precision machining and heat treatment,,the part will outlive most any firearms application we here would ever give them.
Poor quality investments and hardening is a given the part will fail early. It is very, very expensive to have the initial moulds made for the parts to cast the wax masters. So much so that some production is less costly now being done by EDM & CNC from billet steel and end up with a part ready for fitting and or heat treatment.
Forging does add grain structure strength that investment casting does not. But these are hand held sporting firearms,,not the rear end gear drives of quarry trucks.
Investment cast parts are easy to ID by carefull inspection on the inside surfaces. There, the 'as cast' surface will be present in some areas no matter how little as machining them to clean them up isn't worth the time and money. That's part of the savings idea anyway.
Some are more easily seen than others. Some are apparent on the outside surfaces, and some even have tiny voids in the castings.
Not all investment castings are equal.
Ruger couldn't find a decent investment casting outfit to do theirs early on so he started his own (Pine Tree Castings).
