Ever one to there own. I got Saifarland and HKS,all I carry is a revolver. Several years ago I met a man in Fort Lauderdale whose father was one one of the beginners of Miami Dade and Screw one (if not the 1 st) makers for speed loader and now a carry them only.
Assuming Stinger22 means a magazine loader, I'll second Uplula. They are great for dual stack magazines like the 6906 and 5906. There is a Babylula (something like that) for single stacks as well.
Why do you say that? I never have & I haven't had any issues.
.
+1 on the UpLULA, 9mm to 45ACP model. It works great on every semi-auto pistol magazine I own, single or double stack.
LOL, The first time I accidently locked it closed I scratched my head for a minute until I figured out what I did. Now I lock it closed after each use, for storage. That way I get to re-remember what I learned.
