If the charge is expunged, yes. In a deferred judgment, if you meet the terms of the deferment, the judge dismisses the charge, and there is no conviction.
No
No.
Nope
No
If you have a pending felony case, no. If you've been convicted of a felony, no. If you've been acquitted of a felony, then you can.
Yes it could be.
ANY felony conviction is a bar to possessing a firearm in the US.
Yes, if there was no conviction, and the deferred adjudication is not still pending.
No. You are not allowed to have any dealings with firearms period. You can't have one in your home or automobile. You can't have one in your possession. And you certainly can't sell one. Further if you are caught with a firearm while on probation (regular or deferred adjudication) you will go straight to jail. You will remain there for the maximum sentence allowed by your original charge and you will face separate criminal felony charges relating to the firearm. That is all true for new buyers if you are on a deferred felony charge you may not purchase a new gun you may how ever keep the ones you already own. I am on a deferred felony and was asked if I had any weapons I answered them and was told I was not allowed to purchase any new guns or carry them with me until after my probation was up. Regular felony you must turn in your protective devices until you have them reinstated to you by the court. <><><> Minor modification- you may not POSSESS a firearm, but you CAN sell it. You will need the help of a person not prohibited from possessing a firearm. For example, THEY could take it to a gun shop for you, and they could buy the gun from you. But you cannot touch it or have access to it.
You will need the services of a lawyer.
yes
If CONVICTED of a felony, no. However, if convicted of a misdemeanor, yes- unless it was for a crime of domestic violence.
