My front sight on the Talo GP-100 .44 Special is fine. I picked up revolver on Saturday. Just a tiny gap, but hardly noticeable. At the gun shop, there was another GP-100 with that icky green sight sitting next to it, and there was the 'large' gap noted as in posts above. I did check the cylinder gap which is .006. Time to get out my pin gauges I guess and check the throats. Heavy SA trigger pull, but breaks clean. Real accuracy is up in the air, but was hitting the steel out to 35-40 yards (round target and man size) was easy after a zeroing session without paper targets. Gun was shooting high, out of the box. Skeeter loads used for testing.
{edited} I just did the 'lazy man' throat check. A .430 SWC would pass through each throat with some finger pressure. No difference in feel from throat to throat. That's good! And a loaded .44Mag round would not chamber. Oh yeah, after I cleaned up the gun after firing on Sunday, there was no sign of any serious leading (only 60 rounds or so). Just ran a hoppes #9 patch, and then a dry patch. Done. Checked bore with a bore light.
