LL,
Pass on it if it doesn't have the Bisley grip frame and look for one that does, the Bisley grip shape handles recoil WAY better and she will enjoy it alot more.
I don't like the layed back hammer on them if shooting with gloves in winter, it will get caught under your glove every time, then go off when you move you hand enough to let it fly.
My 44 Mag Bisley Vaquero with 300 grainers shoots real well, it also handles recoil awesome.
The base pin pops out (past the detent) on recoil with even 180gr loads and I'll need to upgrade it to a Belt Mountain locking style. If it pops out on you the transfer bar gets cought under the firing pin and locks it up unless the muzzle is held up in the air at the time. Definitely something to keep your eye on if the one you get has not been upgraded with a locking set screw type vs the detent type they come with.
I see them for sale up here all over the place, usually the Bisely Vaquero type though. Usually they're in the $400 range, a bit higher if they've had trigger or jewelling work etc. done to them.
