Gun Report

Guncrafter Industries Conversion Glock Model 21 50 GI, $595

Read Gun Tests Rating and Recommendation

We thought this conversion unit rates an A, but it would benefit from a better base, like the S&W M&P, because of the Glock's limitations. We found the conversion unit to be very well made, well packaged, easy to use, and believe it would be mighty effective for all self-defense uses.

The front end tells the whole story. That’s a real big hole on the 50 GI, yet it's as controllable as the 45 version. The GI slide is a touch wider.
The insides of the Glock 21 are simple, incorporate a fair amount of sheet metal stampings, and feature metal surfaces for the slide-wearing points. The trigger pull in this example was not to our liking. We believe there are other, newer and generally better systems that would benefit from the Guncrafter Industries conversion.
There's not a lot of easily-seen differences between the black Glock 21 45 ACP, top in both pictures, and the stainless 50 GI. The GI's machining and finish were at least as good as Glock's, we thought. The Guncrafter slide is slightly wider: 1.165 inch instead of 1.125 for the Glock.
