Welcome and congrats on the 19. Sorry I can not comment on the 21, but glad you are here
but the 21SF is smaller than the standard 21 correct?good gun. i used to have the g21 SF picatinny model. it is a big gun, but i have small hands and had no issues
by only 3mm's, correct but i have the non-SF g29 and shoot it better than my g19, and my hands really are small lolbut the 21SF is smaller than the standard 21 correct?
