Finally got to the range with my GI 1917. Late '17 or early '18 I believe. Patina finish, but the specks on the frame by the cylinder latch are unburned 231, not rust.
This old girl has the sweetest double action trigger I've ever felt on an N Frame. Target is 6 rounds slow fire double action from 10 yards. Some semiauto shooters had big fun as usual ringing 12 yard steel with her. I put 5 of 6 on a 2/3 IPSC silhouette from 25 yards. Pulled the last one low! Boo, Hiss, Choke!
