Could call benelli and ask if they’ll take it in and give it a try. I’ve sent a couple back to them for repairs... never to remove a choke but you never know. I paid shipping and offered to pay the smith but never received a bill.
I'm afraid this one has issues if there was 8 rounds in the mag... 1 round in the mag... No mag & 1 in the chamber.... SA/DA no matter. It frustrates me every time I've ever tried to shoot it which is why I've historically thrown it back in the safe and forgot about it.
I purchased a .22 mosquito a few years back on the trader, and its never run right. I always run CCI minimags and I have 1 FTF/FTE for every 1 successful triggerpull. I have tried both recoil springs that came with the gun and it makes no difference.
About 2 months ago mentioned this gun's...
Send it back to Stoeger. It may cost you the shipping but they handle warranties/repairs quickly. Not sure they'll give you the warranty based on not being the original purchaser..but you never know.
