In the category of, “Dumb Things I have done” (and it’s a big list), many years ago I traded off an excellent blued, MKII bull barrel.
That particular gun was a very early MKII model (probably one of the very first MKII Bull Barrel models circa 1982) and it shot exceptionally well. I never thought twice about it and just assumed every MKII would make tiny, tiny groups. Well, I’ve owned a bunch since then and they have all been good pistols, but none would hold groups like that early MKII. I don’t know if the tooling was brand new, or the assembly work was done with great care, but that thing shot like a high-end target rifle. I’ve never been displeased with a Ruger Standard Pistol or MKII, but I sure wished I had held onto that particular pistol.
Oh well, hopefully it landed in a good home.
