ill make this very short and to the point, ten minute kick out is crap on a website.
If handguns were not allowed in any way at this range, the range officer would have legally been required to tell you that when he yelled at you for doing draw and shoot drills during your first range visit.
Since he did not say no handguns period at this range you are in the legal right to possess and use a handgun at said range. Untill the people in the range office post a sign in the front office next to were you sign in stating no handguns.
Strange enough, the DNR does have the right to say what weapons and projectiles are allowed at a range they own and run. Its law.
However since noneof the above happened, you can only surmise that handguns are allowed.
Furthermore what happened to you during your second range trip, and the purpose of this post is a crime most jurisdictions list as
Armed felonius robbery/assault based upon the circumstances.
1. he was armed
2. he stole an item from your possession.
3. the item taken was located on your body, hence assault because he touched your person
4. assault because he obviously pointed the weapon at you.
even in the most screwed up jurisdiction in even chicago, you had the legal right to stuff your rifle barrel up his nostril and use deadly force as he was perfectly ready and able and capable of killing you then and there.
Legally speaking he had no legal right to seize anyones weapons, not even if it was a sawed off shotgun with a 3 inch barrel on it. Unless hes a sworn in peace officer,state game warden, or a member of the federal police ie, fbi us marshall or atf, he has no right to take it.
please avoid this place, its obviously an unsafe place to be as any intelligent adult knows that grabbing someones gun can and will most likely leave the grabber on the floor dead or dying of multiple gun shot wounds.
At this time contact the DNR office in charge of running gun ranges and start complaining. If that doesnt help, talk a cheap lawyer on it, and if the see a miscarraige of justice, pursue legal action to get the person punished. After all having a gun shoved in your face is extremely traumatic and debillitating psychologically.
