I've gotten into them a time or three to get some dirt and crap out, and to install the speed strip kit in my 22/45. I had to put a different hammer in for that to work. If you remember the exact sequence and pull the trigger, tip the gun first one way then another and gently shake it back and forth, all at just the right time, as you insert the mainspring housing or whatever Ruger calls it, then it's not too bad. But I haven't done it enough to memorize the right sequence and can't get it right the first time, every time. One thing I do know is that a paperclip is a good tool to pull the latch out to take it apart, but a loop of any plain old wire works even better. You can make a loop big enough to use your whole hand. No more scratches or gouges to the metal from prying at the latch with a screwdriver. It seems like there was something else I used too but I can't imagine what it was.
