Not meaning to hijack the thread, but why would anyone want a DAO pistol? What "need" was meant by producing them in the first place? Try as I might I just can't logic my way thru that one.
Many thanks for the responses. I wouldn't necessarily mind the SA, but a PC model is surely going to to be well out of my budget range. Looks like I'll have to settle for a 4" barrel or - more likely - go with a .45 and get the length I'm really wanting here; I don't think a 10mm is something...
I really like the look and feel of the 4506 but I don't particularly want a .45. Were any other pistols in this style / series produced in other chamberings (and relatively easy to find) with a 5" barrel? Or did that barrel length only ever come on .45 caliber models?
TIA :)
