The only complaint that I have ever heard leveled against the model 21 is regarding the size of the pistol’s grip.

Well that and its the size of a mini cannon that unless you're decked out like the Michellin Man you can't conceal carry it :)

The size factor is what I was interested in. Now it turns out that the slide in the production model 37 is not as narrow as the prototype, which was billed as being the "size of the Glock 17". Therefore, it hardly seems like a real breakthrough for gun manufacture. It remains to be seen if this will become a commercial success. If one could convert it to shoot .45 ACP, then it might be more interesting. I think given the size of the upper end, it might be possible.

You can CCW a Glock 21 if you know where to place it on the body. I have carried a 21 on numerous details in both a belt slide and shoulder rig in cold and hot weather. Placement and clothing choice is the key and I am nowhere built like the Michellin man. Besides 26 rounds of 45 ACP from 2 pre-ban mags and 10 rounder just in case sure makes some sweet music when needed and says you are ready to go!

As for the 45 GAP round: cost too high, not readily available in a pinch, and I think you will give up something in the amount of powder you load into the case. Although a 45 round you want move slow instead of fast so it will give up its terminal velocity upon impact.

I like to carry something small with a punch. I found it in the Taurus MILLENNIUM PRO PT145 .45 ACP
