My club has an "Action Pistol" meet once a month. More defensive-based than competition-based. Retired cop sets it up and it is free to club members. Maybe a dozen members will show up and he'll usually set up 3 "stages". No score is kept and it is more like "Who's next?" "Who hasn't gone yet?" "Who wants to go again?". Most of us will go at least twice and I'll usually go weak (left) hand only the second time. I should probably refer to my left as "non-primary" because it isn't really any weaker than my right hand...
The last stage consisted of kneeling behind a barrel (on the left that you can barely see), engaging the two closest targets at least once (I did three times) then back up on feet and approach the second barrel with gun up aiming, then back down on knee(s) and engaging the last three targets at least once. My second time through was weak hand and at the second barrel I ran the gun dry. Fortunately the slide locked back so I put the gun on the ground magwell up (keep in mind I'm kneeling) and stuffed a mag in then gun in hand, hit the release with my left index finger. It was interesting reloading "under pressure" with left hand only but I got it done...

I don't know how I would have racked the slide if I had to without making the RSO nervous.

I mean, I KNOW how to rack the slide against something but I wouldn't want to run afoul of range etiquette by being unsafe...
