For the upcoming article in Concealed Carry magazine about .22 adapters and rimfire clones of centerfire guns. This Iver Johnson set has .22 for practice, 9mm for competitions and 45ACP for carry.

    Had no idea the Iver Johnson name was back, though given how much they are trying to distance themselves from the old incarnation, I have to wonder why they did not just go with a new name entirely…

    Rather than purchase an expensive modification for my beloved M1911A1, I practice/warmup with my Ruger MkII Bull-barell. Those .22LR adapters cost as much as a new pistol, might as well just have a seperate pistol.

      True — but mk2 manual of arms is very different. Adapters allow the forming mostly the same handling habits as with centerfire ammo.

        Isn’t that the benefit of Ruger’s 22/45? Same grip angle and location of safety, slide and magazine releases.

          I have a 22/45 and it’s not even close to 1911 manual of arms. For one. Slide cannot be released by pulling back on it, a (very stiff) slider in the frame has to be used. It’s a decent stand-alone pistol but not a suitable trainer for a 1911.

    Oleg, changing calibers on a 1911 is not as easy as it sounds. While most .22 cal. top ends can be switched on the range, the 9mm and .45 ACP models require different ejectors, which are frame mounted. To change the ejector you have to knock out a tiny pin and lever off the ejector, which is beyond the capabilities of the average shooter and hard to do on a range.

      I didn’t mean interchanging 9×19 and 45ACP barrels. Those I know cannot be swapped quickly — that’s why I am showing two frames and an extra upper.

    Hmm. Are they gonna have a Commander version? The “new” IJ has for a couple of years sold what I hear is a fair rendition of the steel-frame Commander, though I have not had the opportunity to examine one firsthand. And I am not sure at first blush whether these replacement top halves could be expected to fit a Commander frame perfectly, given its shortened dustcover.

    I can tell you that steel-framed Commanders in 9mm handle nicely and are great fun to shoot, though. I am likewise intrigued by the .22 conversion kit, though for the past couple of months .22 LR ammo has been even harder to find here in my neck of the woods than 9mm or .45.
