I been shooting one the last few days several hundred rounds through it. seems to be accurate only malfuntion is failure of the slide to lock back on last round once in a while.

Isn't my gun don't know the last time it was cleaned.

feels nice handles well.

I have one also. With a red dot on the top. Great hiking grouse gun. Your failure of the slide to lock back is likely a magazine issue.

I think was more a failure to clean and lube borrowed it from my brother whos to busy to clean much. I cleaned and lubed it I'll take it out next week again and try it.

I am looking at one for sale right now....
Any thoughts.....I was impressed learning that it was made by Hammerli....
