I'm learning my way around taking care of a handgun but couldn't find an answer to this question, maybe you guys can help me out.
If I replace a factory barrel in a semi-auto with another factory barrel of the same manufacture, do you need to check headspace due to the barrel swap out? What about after-market barrels, do you need to do a headspace check if its a different manufacturer? Its my understanding that changing barrels or bolts in a rifle, you would need to do that, but I don't know about pistols. |

Quoted:
1911 style and xd9 style I emailed Springfield a while back asking if an xd45 tactical barrel (5") would be able to drop in a service model's slide (4"), they said no, because their barrels are fitted to the slide. I eventually bought an xd45 tactical and tried to drop it into my xd45 service, but the tactical slide wouldn't lock up. It seemed to be too tight. |

Handguns don't require measuring for headspacing, generally. Many headspace on the extractor hook, some might on the casehead itself, but I don't recall which ones those would be.
If a rd is too short for a chamber, then it'll just rattle around in there & not be accurate. If it's too long, the slide won't close & the gun probably won't fire as it's out of battery. Since a bbl almost always has the slide catch going thru it, there's not much room in there for error, IMO. A bbl's hood & lugs will need some slight attention in most guns. My .o2 |
