There’s not very many .50 caliber pistols being manufactured out there, and it’s a shame. So I did a bit of research and have listed the ones I could find below.
The 50GI is a low pressure round that doesn’t give you a big concussion blast like high pressure rounds such as the 10mm does. This makes it more tactically sound in a firefight. The 50GI case was designed with a .45ACP case head size which allows for a barrel and magazine swap so either round can be used in the same pistol with only a barrel and mag swap. This further increases its versatility and value.
This pistol comes with different barrel lengths. Personally, sometimes size does matter! But then again, if you have to conceal a pistol, you can enjoy the same quality 50 caliber pistol from Smith & Wesson but with a shorter barrel and different purpose.
The Desert Eagle was the first 50 caliber pistol I was able to fire. When I think of a .50 caliber pistol, the Desert Eagle is always the first one that comes to mind. On top of that, my choice is always semi-auto over revolver.
I’m not so sure that AMT still manufactures this pistol, but there are some still out there on the market. It holds six rounds and would sell on the open market for around $800 US.
I know for a fact that the Grizzly WinMag is no longer in production and all models are sold out. However, it seems as though Grizzly still offers parts for it. Grizzly seems to be moving more towards their .50 caliber rifles in production.
