Bill I actually never had a problem. My 27 I used for IDPA always worried me about something getting in the the recessed area of the recessed cylinder. But I just kept that recess clean in between stages. My 24 is not recessed. I have been looking for a K frame to start playing with, like you and I discussed over a few emails several months back. Mmany of the 19's I have seen had recessed cylinders, and I think I want to stay away from that this time, and get something a little newer, or a 38 sp which was never recessed.
