Headspace question

[shamrocks]

Thanks Mike. I 've been experimenting a little here. Put a shell in the chamber by hand (no housing or hammer or firing pin so it's safe) and worked the slide. It may just be okay afterall.......when releasing the slide from full back it goes fully closed in battery and ejects the round when I pull it back, but if easing the slide forward it stops.
Didn't make it to Raleigh..had a family emergency but that tool worked like a charm installing the sight. Thanks again.

The potential problem still exists. The carbine headspaces on the mouth of the cartridge. If a longer round is forced into battery, the bullet will be crimped tighter into the cartridge. This will raise the pressure, possibly enough to cause a failure. My bottom line: don't fire until the headspace is within specifications. You might fire 10,000 rounds with no problem or you might have a problem with the first round.
