One question we get frequently to rules@uspsa.org is around the use of suppressors, or more specifically, why we don’t allow them. Most of the time the person sending the query is upset that we are infringing on their rights. Nothing could be further from the truth.
Okay, so what about suppressors? Why do we disallow them? It is simple, really. In our sport we use timers that function on the report generated by the discharge of a cartridge. A suppressor makes it just that much harder to reliably get a correct time on our timers. Some PCCs in some situations, and especially rimfire rifles in SCSA, are already notoriously difficult to get shot times on. Failing to get an accurate time necessitates a reshoot which slows the whole match down. Yes, some timers can be adjusted to pick up just about anything including dry fire at home. BUT, when you do this they also start picking up shots from adjacent bays and other noises. This also negates an accurate time. Many of us also own suppressors and all of us have been around them and we know that there is a substantial difference between “Hollywood suppressors” and reality, especially with center fire calibers.
Neither of these prohibitions are about being politically correct or suppression of your rights as a gun owner. They are rules, within our sport’s rulebooks, and we have to enforce them. You are free to own whatever you want to own (and that your state will allow, apparently). It just may not be legal in our sport. We also don’t allow burst fire, full auto fire, incendiary ammo, tracers, and all sorts of other fun stuff. The rules are the rules and we compete within them.
