Back in 1991 I got a "Quickie Comp" system for my 1911. The recoil spring has never been changed and it is a captured type. It also isn't the typical 1911 size spring. It is shorter and the inside diameter is smaller too. It doesn't have a bushing, instead the barrel tapers up to a bull barrel at the end right up to the threads.
I have a reciol spring tester on order to try and figure out the poundage but for the rest of it, I am at a loss.
The round that I am pushing out of it is a 200gr Extreme round nose with 7.8gr of Auto Comp. It chroned between 950 and 985.
Any help will be greatly appreciated.
