I have an AyA that appears to be ammo sensitive. It shoot Fiocchi and Remington Gun Club just fine but others make opening the gun very difficult to open.

This is an extractor gun. Is there an easy way to see if it is due to the base expanding enough to keep the extractor from moving or the firing pins sticking in the primers.

There are a lot of folks far more knowledgeable than me on this site so I thought I would see if I could tap some of that expertise...

Thanks,
Don
