Fragmenting or dislodged caps can cause a jamming problem in any cap n ball revolver, but, the Colt models are particularly prone. If a cap is dislodged from a loaded cylinder, stop shooting immediately! An exposed nipple on a loaded chamber is an invitation for a chain fire. To minimize the possibility of a jam from a fragmented cap, or, dislodged cap on the fired chamber, get into the habit of smartly raising the revolver to a vertical position while cocking it for the next round. this will throw the cap away from the action rather than allowing the fragments to fall into it. The channel in the recoil shield was designed to help with this problem, but many of the replicas have a poorly aligned groove, or, one of insufficient depth or poor design. At any rate, a fragment, or entire cap that falls between the hammer and frame will surely be a problem. Manually throwing the cap or fragment away by raising the revolver is a period correct precaution against that type of jamming.
