two reasons:
1) Ruger SR1911 Lightweight Commander
and
2) Rock Island 1911-A1 CS
So no downgrade just a readjustment from three .45acps to two .45acps and a 9mm.
I had to trade in my SR1911 .45acp for it but it was worth it. Love everything about it.
Shoots just fine. Can't wait to get used to it. Shooting 147 grain with no problem.
