I concur,
There is a tendency for lead and carbon fouling on the frame above the cylinder
right at the gap. On a DW .22, after about 300 round ( all lead of course) there
was enough to nearly stop all action. I actually used a wood "popicle" stick
that I sharpend to clean it with out scratching. I have ha carbon build up on
the .357, but never severe.

barrel gap slightly to keep shooting. Enough soot had built up there to cause
the cylinder to hang. Once I got the DW home I gave it a thorough cleaning,
including using a spray solvent that removed all of the existing lubricant along
with the grime. I re-lubricated with very little gun oil and I have not had a
similar problem since then.
