I did it and I don't know if im glad or not? wile wondering around a gun shop in this area, I spotted this thing in the back of a show case and ask to look it over, Used but no obvious ware and the darn thing just fit my hand SOooooo for $375 I now have my first 9mm! Daewoo DP 51. Anyone have a like piece or any info on this little critter? For sure it looks like a S&W (DA/SA) bouble stacked.
