I did search but could not find out specific information- I know that all three use frames and slides from Armscorp - I also know that RIA WAS dist of Armscorp and it is now CITADEL. STI uses thier internals - and are in Tx so that is nice for me to know. My quesiton is this - RIA, CITADEL - is there really any difference between them to justify cost difference for a compact (I have seen a 150.00 - 200.00 price difference with Citadel being more)? This is in regards to reliability and quality. It is my understanding that Citadel is new dist for armscorp and gunbroker has several examples of each but it seems that Citadel has "upgraded features". My issue is that if both are the same then I will just get the RIA Compact - but if there is a difference I would like to know so I can make an informed decision. RIA compact and Citadel Compact images attached for comparison This is going to be my first 1911 in approx 15 years - any information to clarify my understanding would be greatly appreciated.
