As you’ll recall from my review of the BUL Impact, I loved the pistol, but bemoaned the lack of a way to get a nice flush fit with the full length BUL M5 9mm magazines. There was a product image showing a sleeve adapter, but I had never seen one in the wild.
Well, if you can’t buy it… you build it. Or in my case, you 3D print it.
One of my “grail guns” has always been the BUL M-5 Ultra-X, dating from my first year of getting into firearms. I’ve always loved its combination of compactness and firepower. For a long time, I had been holding out hope of getting one in 9mm, but it became clear through my research that if any Ultra-Xs in 9mm were ever imported, it was probably vanishingly few. I settled on a Charles Daly .45ACP model that a reader offered at a good price.
My thoughts? Read on!
One mystery that consistently driven me a bit crazy is the subject of whether BUL M-5 Ultra magazines are compatible with the BUL Impact, and vica versa. I finally have an answer. As you can see in the above picture, the difference between the two magazines is the follower. The Impact magazines (seen on the right) have a slightly different follower with a higher left hand side to push up the Impact’s slide stop. The M-5 magazines (on the left) have a “normal” profile follower without the raised edge. You can use either magazine type in either gun, but the M-5 magazines won’t actuate the slide stop on the Impact, and the Impact magazines will require more force to release the M-5’s slide on an empty magazine.
Given that proper Ultra-X magazines appear to be going for astronomical ($100+) prices these days, being able to use DDA mags should be very financially helpful to owners of the Charles Daly M-5 Ultra-X and the Kimber Ten II Ultra.
