1911 in . . . 44 mag . . . really!
Really, really!!
I used to have one, blued, 6.5" barrel. The Wiki article gets it mostly right, except that mag capacity in .44 Magnum is 6 (six) rounds, not 7, due to the slope needed to prevent rimlock. In .45Win Mag, magazines hold 7 rnds.
It is a high quality 1911A1 on steroids. Stretched and strengthened, though there are some 1911A1 parts that will interchange, many will not.
In standard configuration, compared to the .44 Mag Desert Eagle (which I also have), the LAR Grizzly comes off superior in all but two aspects. And those are magazine capacity (.44 DE holds 8 in the mag) and recoil.
The Grizzly is about a pound lighter than the Desert Eagle, so there is a slight difference in the recoil.
BOTH have a felt recoil significantly LESS than .44 Mag revolvers, due to their weight, and grip shape.
Compared to the .44 DE, the Grizzly is lighter has a 6.5" barrel compared to the DE 6", has the excellent 1911A1 trigger, and a thumb safety one can actually reach (and on the frame where it belongs, not on the slide, and working in the "proper" manner, down for off, the opposite of the DE).
Pachmayr grips were standard, providing a superior grip than the stock DE, and the slightly smaller grip frame size makes the gun feel solidly "locked" into my hands, better than the DE (and also better than the actual 1911A1, for ME).
The Grizzly also came with excellent fully adjustable sights (Millet??) standard. The DE does not. Millet sights are an aftermarket option for the DE.
And, being recoil operated, the Grizzly has NO issues shooting cast bullets. The DE (due to its unique gas system) should NOT be fired using cast bullets.
I haven't had a .44Mag Grizzly for some years, I traded mine for a .45Win Mag Grizzly.
I had occasional feed issues with the .44, have not had them with the .45, and it holds one more round.
Accuracy is on a par with any high end well put together 1911A1, (will put 5 shots in one ragged hole at 25yds, if you're up to it) and long range accuracy is excellent. Regularly ring the 200yd gong on the rifle range, if you're a good enough shot.
I have Auto Mags, Desert Eagles, a Wildey (.45WM), the Grizzly, and a Coonan (.357mag). If you want big bore magnum performance in a semi auto pistol, the Grizzly was (is) the most practical overall.
LAR stopped making the Grizzly some time ago (Wiki says 1999), which I always felt was a poor decision. According to what I remember from the time, LAR made a corporate decision to drop the Grizzly and concentrate on their .50 BMG rifle instead.
My last range outing with my Grizzly was to meet and compare it with a fellow who had an Automag IV .45 Win mag. After firing a single magazine through the Grizzly, he asked if I would be willing to trade, or sell, mine. I smilingly, declined.
