Just wondering how much accuracy you lose from going with a 4" barrel instead of a 5 or 6" barrel. I want something small enough to conceal, but i dont want to lose accuracy.
BTW, i am leaning towards a glock 21 or 30...or an XD45 (dont know what barrel length) |

True accuracy? As in, from a machine rest? An imperceptable amount, if any. This is given the same construction, etc of the barrel. (No point in comparing a high grade barrel of one length to a low grade barrel of another)
In practical use, barrel length will most affect accuracy as a function of sight radius. Shorter sight radius will results in reduced attainable/practical accuracy. An extended barrel beyond the slide - thus not affecting sight radius - would not yield any usable benefits in accuracy. (Benefits of such extentended barrel set-ups are the ability to thread for cans and to be ported for recoil compensation, not accuracy.) |

Weird though. |
