This looks like a KMK4BL but it is not. The serial number comes back to a 00167 that shipped in 2000. It is marked 22/45 but instead of being on the plastic Zytel frame it is on a standard Mark 2 stainless frame. The trigger is not gold like a Lipsey model. The Ruger Eagle is on the back of the bolt. The box is green like a Lipsey box but the manual inside is for a Mark 3. The label on the end of the box is partially missing so it is not able to give any information. I wonder if it was made that way at the factory or is something that someone put together. There was a mismarked 22/45 in a previous post that came back as a KMK512 and was marked as such on the box. Perhaps Chad or Don can shed some light on this one.

sorry about the double pic!

My guess someone changed the grip frame .

yes, obviously a "swap",,,we did one like that using the 5 1/4 in tapered target with the stainless MK II grip frame,,,that was NICE!!! should have kept it....we did cut down quite a few 8"onch,even some 10 inch guns for customers down to 5 or 5 1/2 in BULL barrels easy to do with ANY of the target bull barrels semi autos...trick is to mark the front sight location BEFORE you make the 'cut',,,,,

Swapping grip frames & such is quite common. Lots of folks buying custom top ends & using the guns in competition. I've bought a few boxes of "parts" and found I was able to assemble complete guns from just such projects. I have one in my stable I call the "FrankenRuger" because it's an assembled parts gun.

yeah, stranger things have happened, but no way to prove.

Could be a FrankenRuger but in any case it is a nice pistol. Thanks for the input

Seeing that it is a FrankenRuger I think it looks good with black and grey laminate grips. The blade is a Case Ruger Lightweight SS fixed blade
