I had previously opined that BUL had never released the “official” factory mag sleeve for the BUL Impact. Apparently, this was not quite true, because a pair of 9mm BUL Impacts being auctioned off by Mach1Arsenal on Gunbroker have them:
These appear to work like the 3D-printed ones that I’m using – slip over the top of a full size magazine and just slide them down. There’s no locking mechanism at the top of the heel of the sleeve, which I had theorized might be a way of keeping it permanently connected to the grip. Unlike in the official shots, this sleeve doesn’t seem to be pinned to the bottom of the magazine. It looks to me like these sleeves are what would have been the bottom of the Impact’s grip if it were full-size.
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.
One of the real oddball guns made in Israel is the BUL Impact. Everyone loves a double stack 1911. Everyone loves the CZ-75. So what if you took a compact polymer CZ-75 and grafted a 1911 double stack magwell on it?
Well, you’d have a BUL Impact. Read on for more.
