Thanks for the info. btw, I received my Remington 148's. thanks.
you probably know more people using 9mm in RO 1911's than I do, have you noticed them to have a faster rate of loosening up compared to a 45acp 1911?? My gunsmith noticed a SA range officer in 9mm that he did a trigger job on and redid the barrel bushing and installed a bigger slide stop pin to tighten things up has loosened back up in maybe 1000 rounds at most. He started with a factory fresh gun and didn't really do much but to have it loosen up kind of surprised him. He has a full custom built one on Caspian parts and it has not moved since building it after over a thousand rounds. The one he built for me hasn't loosened up but I don't shoot it much.
Just wondering if anyone has seen this in SA 9mm's. thanks.
