It is not "if" but "when;" and what follows "when" is "how bad." Maybe you'll be careful enough. We're all seen the reports from people who were not; the link is to someone who was and it still made for a bad time.
The gun-cleaning/clearing area at Roseholme has not had a sand barrel but it's going to. It's too easy to become careless and every little bit helps.
Also, note that in the linked story, the gun was believed to be unloaded. They never are, not until you have it field-stripped and maybe not even then; but we get casual. The guys that taught me to shoot handguns made a big deal about checking the chamber with both eyes and a finger -- not just to "make doubly sure" but also on the theory that you might, just might, be reminded to slow down and pay attention at that critical step.
