Picked up my new 605 Poly Protector on Sunday Night. Brought it home and gave it as thorough of a cleaning as I could. Monday morning took it to the Range. FIred Blazer 158gr JHP, Handload 140gr Jhp, and Handload 38 Spc 125Gr JHP. I fell in love with the revolver, at least when it would work. Occasionally it would seem that the revolver would lock up and not fire, on all three loads. In working with it I found that I could get it to cycle if I pulled the hammer back, with great difficulty, and set it up single action. At that time the single action trigger pull would become horrendous, and once it took a left and right finger together to discharge.
In inspecting my brass at the range I saw some scratches on primers for the rounds that were difficult to fire, so I figured it may be due to the tight tolerances of the fire arms, and maybe some high primers on my handloads, but this didn't explain all the malfunctions.
Upon returning home I inspected all my brass after tumbling and I found scrape marks on the edges of many of the rims. Removing the cylinder and inspecting the back of the firearm I saw brass scrapes on the top near the firing pin and the bottom. Pulling out my magnifying glasses I saw that there were definite height variations in both locations.
Using a fine file i spent 3 hours gently lowering the high spots on the top and bottom until they were almost flush with the low spots. I would periodically check the tolerances by running 30-40 brass pieces through and check the cycling. After this work I was able to cycle all the brass without issue.
I need to take it out to the range to be sure, but I may have solved the issue. Now I will just need to blue the areas I worked on.
