What has been your results with a hammer extension on the 301T .410? I have read in years past, that there had been some misfires due to it slowing the hammer down. Is this still occurring? If you have not having any problems, what particular brand(s) have you guys have found that work well without having to do modifications to make it work?
I've used them on all my Thompson center guns for years with no problem. If your using a scope they can give you that quick access to cocking due to clearance issues that arise. I had one on a 410 model 301 and the child using it had no issues.
The one that works the best is the Uncle Mikes number 2456-0.... Hammer Extension...
Thanks guys! I really appreciate the info!
