Aside from what's already been said...be aware and bring it up to the host well before if there's game conditions specifically related to pistols.
i.e. If there a rule such as pistols only in buildings. I think the LZ used to be like that.
If in question...put that question to the host. Final say is up to them.
The spirit behind any rule/limit/etc. is to establish a upper safety level. It's never been about establishing a level playing field.
However...I think that pistols have mostly been dismissed from being listed in limits since they historically were shooting 300fps +/- just a little and so not a safety concern specifically.
