My other 1911 is an RIA. It sucks as far as quality of slide and frame and fit and finish but it has ran like a top for 10,000 rounds.
The difference between "MILSpec" & Wilson Combat/high end 1911's is HUGE...
but due to MILSpec's loose tolerances which allow for excellent feeding,
eat-anything attitude, and No Headaches At All, RIA does it better than many.
Whereas, once you start tightening tolerances to WC levels...
they get increasingly ammo-finicky,
more prone to lock-up due to dirt/dust/etc...
and you have to increase maintenance to deal with all those issues.
Basically it's the same AR vs AK argument in pistol form...
which do you prefer?? Laser precision accuracy or flawless feeding??
Either will still kill the bleep out of a bad guy...
So they both win
Preference is a well-cared-for pistol that I know the habits of...
because when you know exactly where a given pistol
is going to shoot with a particular ammo,
that's reliability you can bet your life on
Besides, if you slap a WC Bushing on a cheaper 1911,
they tighten right on up to some very nice groupings
