Out of habit and convenience, I use R. J. Hedley's "Two-in-One Stopstick" and Steve Bedair's compression tool to align the slide and the barrel pin for take down and reassembly. I can perform the entire process without any tools or the well-manicured "third hand" of my little wife who helped out the first few times I cleaned the R9, but at my age and station I say to myself, "Self, make it easy on yourself."
