Single Stack


Recommended Posts

Do we know yet if Single Stack will be made a permanent division? I'm sorry for my ignorance, I let my USPSA membership lapse and haven't shot in a few years (until TODAY!!!). When I last shot, there was no such beast but I shot the division today. I'd like to make it my permanent division, but not if it's going away.

Is there anywhere besides USPSA that I can find the rules for single stack division? Maybe it's spelled out somewhere on these forums but I can't locate them.

I seemed to be banned from the USPSA website in Canada :(

I'm planning to build a new 1911 and want to be sure what I do fits the rules...

Anyone...? Is there a later update to the SS rules than the 2006 update? If so where is it to be found? I want to make sure Trickpony get the latest. :cheers:


Merlin, 2008 rulebook is here. That's what you need. Single Stack is Appendix D5. Starts on page 76.
