I thought I should post an update on this,
I contacted VTI about getting a new bolt, they informed me that the correct ASM part was not available, and a Uberti bolt would be too short to work properly,
so it appears that is what someone did, the tried to use a Uberti bolt, with no other recourse I attempted to make the bolt I had work as well as possible, first thing I did was remove some material from the frame and the bolt where they contact each other in order to get the bolt to protrude further out of the frame, I was able to get a fair amount of additional engagement with the cylinder stops this way, I also increased the spring tension on the bolt,
of course this threw off the timing, which I then corrected, but I couldn't figure out how to add a hammer stop,
at this point the revolver was working better, not perfect but better, and that is how it stayed, at least for a while
recently I saw a youtube video by gungoon about fanning a cap and ball revolver, in it was a pic of his hammer stop mod, I immediately grabbed my Dragoon and ran out to my drill press, I had gotten stuck on stopping the hammer, I never thought about stopping the main spring, this mod works great and is invisible when the revolver is back together,
after adding the stop, it occurred to me that chamfering one edge of the cylinder stop, and beveling the edge of the bolt would allow the bolt to engaging earlier, and BINGO! it is FIXED! it works 100% now, the bolt catches every time, no problem no matter how fast I cock the hammer
