I shoot an STI Edge, so the length will be longer. When I shot the La Gator in October my load chrono'd at 174PF, 200gr Bayou, 1.185"oal 4.7gr WST. When I was shooting my Glock 24 with a KKM barrel it liked a 1.13 oal. If it were me I would make up some dummy rounds at varying length to see which are the best length for your barrel.
