I am also having issues with my 43C. I bought it just after Christmas. First trip to the range and with a variety of ammo, it shot six to eight inches to the left at seven yards, spit lead ferociously, and all spent cases required major effort to eject even if allowing the cylinder to cool. Warranty had it for about eight weeks. The cylinder was replaced, forcing cone recut, some other things done. Still shot way left with everything and spit a little lead, but not as much as before. I sent pictures of the target and told them I especially wanted it to shoot POA with Federal Punch. Got it back a little quicker the second time. Barrel adjusted, forcing cone recut. It now shoots about an inch or two left at seven yards with everything, and I still get spatter in the face with some ammo. If I keep having to send it back, at some point I will have an less than one inch barrel due to recutting the forcing cone each time. I ordered a new set of grips to see if the way I'm gripping has anything to do with the stock boot grips and pressing left. If that doesn't show any improvements, its going back a third time. I have an old 18 and 34, and neither have the lead spitting problem this little gun has exhibited.
