i know the glock 20 has a heavier slid. i bought i glock 21 barrel a i can see that the top part is abit to wide for the side i like to know if you had it shaved down to the same size as the glock 20 barrel would it work??? and why no glock 20 .45acp barrel conversion kits?? i thought 10mm was faster the .45acp and more psi to also. it seem to me that drop in barrel to .45acp would be nice change to the glock 20 . its getting hard to find 10mm. thinking of buying the .40 conversion barrel also. the one on the right is the glock 21 .45acp barrel
