The ROC in 9 is a pretty good deal-I have the 45 version, springer did not get the memo about short 1911s being unreliable. Mine has been 100%, and a friends 9mm version has also been 100%.
You gotta know SA had to cut some corners to get them this cheap though. Fit/finish is just OK.My thumb safety was razor sharp. My trigger had more creep than a child molester, and the damn thing was nearly a foot high/left. Sent mine back and SA cleaned up the trigger and got it shooting to POA,no charge.
My buddies ROC 9 is going back since his front sight will not stay in its dovetail.
Still really nice CCO for the $$
ETA- JMB designed the gun over 100 years ago, the last 20 years have really seen some improvements. Guys who know what they are doing have pretty much figured out how to make small 1911s run.
