Well, I decided to go back to the smith that looked at it originally and purchase a pin that worked in the gun. I purchased the pin as a back up. It seemed much thinner than the one that came with the gun. I then trimmed down the diameter of the original pin. After the trim I placed the pin and spring back into the slide and tapped the rear of the pin to see if the pin would get stuck. It didn't. I assembled the pistol and put about 200rds through it.
It didn't get stuck in the hole but it did get stuck behind the firing pin stop. This happened about 6 times in the last 50rds. This never happened before so it has to be the way I trimmed the pin. For now I'll drop in the new one until I can figure it out.
Thanks for the advice
