Home Forums Hunting & Shooting Rimfires Mark IV lower swap?

Maybe some of you know... are the lower of the Ruger Mark IV pistols interchangeable? For example, could I swap out the standard lower with it's Luger-angled grip for a Mark IV 22/45 lower and keep the same upper?

Rocky Mountain,

Don't have the non-22/45, but they are the same attachment, and the same upper/receiver.

I've got a couple of barrels for my MK4 22/45... takes about a minute (or less) to swap them out.

Yes, the Mark IV and Mark IV 22/45 lowers/uppers swap around. I have a Mark IV Standard (skinny barrel) and thought I'd like to try a Target 22/45 so I bought one of those. Found that I did not like the 22/45 grip angle but did like that target barrel so I tried popping the barrel onto the Standards lower (and vice versa) and it works just fine. Searched for a non-22/45 lower only but from what I was seeing online those cost about the same as an entire new pistol. So now I need to either sell the 22/45 lower or pistol as I won't ever use it.
