Great thread
I have not had the opportunity to shoot many of the high end pistols here but have shot a few pistols.
Shot:
SIG 226 9mm, SIG228 9mm, SIG239 9mm,
Glock 26, Glock 19,
Beretta 92, Stoeger Cougar 9mm,
RIA 1911 .45acp, RIA 1911 9mm,
Ruger SR9c,
Colt .45acp, Caspian .45acp
and ...my new Kimber Custom II .45acp.
Of the above, my new Kimber Custom II is the most accurate centerfire, followed by the Caspian. Perhaps even. Really love the Kimber.
Amazingly accurate for their size were the Ruger SR9c and Glock 26, for some reason. More than the G19 or SIG 226 (which was old). Both RIA's were excellent for the price.
Most accurate rimfire would be my Ruger MKIII Hunter, 4-5/8" barrel, stainless. Better with it than any other .22lr I have tried..though have not tried a Buckmark.
My best to all
