Re: Trapping Pistol
I had an old H&R 922 that I used. It was essentially junk like most H&R pistols that I ever saw but it did the job. I was never too concerned if I dropped it in the creek or it got mud or blood on it.
Most shots are going to be pretty close so you shouldn't have too much of an issue with shot placement with or without a scope. I suspect any .22 should do the job.
