I got the 22lr version, do not care for it in 38/357 because there is trigger reset/slack, I have had it not reset and missed a chamber once or twice.
The 22lr does serve exellent trainning purpose for me on the DAO revolvers. Felt a 22mag at the gun shop, the trigger must be 3-5lbs more. Factory settings for 22lr is about 7.5lbs? mine came in about 7.5/8 very smooth!!!
