Field stripped and cleaned before loading the 1st round. The oiliest new pistol I've ever purchased. Fired a total of 250 rounds my 1st outing. 185gr JHP Montana Gold rounds, 200gr SWC Precision reloads, and 230gr RN Bayou Bullitt reloads, 230gr Win white box factory rounds. All ran with no issues whatsoever. The only 1911 except my Springfield Champion that ran everything I shoot without an issue. I'll run another 250 rounds this week and she should be broke in. Likes the 200gr SWC reloads. Nice clean groups.
