I would prefer two piece also, though I do like the appearance of one piece. For the bp shooter who might want to remove the grips for cleaning after each use, all of those grip frame screw heads are bound to show a beating pretty soon. Something I have considered was covered in an old G&A (?) magazine article many years ago, snap apart grips. The writer had split the one piece grips, as mentioned above, but instead of installing an estucheon he used fibreglass to install a line 24 snap between the two halves. The appearance was that of a one piece grip but the disassembly was a simple snap apart. I will try to find the old article the next time I visit the shop and check for any other details if you are interested?
