Beretta 686 Issue

[Sako300]

Hi,

I bought this gun used about two years ago and on a few occasions while out hunting the firing pin does not seem either strike the shell properly or hard enough (not sure) or it fails to fire, almost seems like the safety is on but in fact is not. A lot of the times it will fire the bottom barrel but not the top.

Either way wondering if anyone else has experienced this issue or if you could recommend a good gun smith in the Calgary area to take a look at it?

Thanks in advance.
