It has some oomph behind it. I haven't chronographes any loads but recoil can be snappy. 

Image below from TJ Parmele - Image Title: Smith 1917 Converted
Image Info: This is a slightly different version of a Smith and Wesson 1917. Barrel has been changed to something akin to most likely chambered in .45 Colt. The surface also looks to have been re-finished in a black oxide. Trigger is ok. The Double Action lockwork needs smoothing up and I am probably going to replace the stocks.
