I have a glock 21c for the nightstand and shoot it pretty well. I am currently looking for a new ccw and am not sure what to get. Where I live, I cannot rent guns to shoot at a range so I have to go on feel alone. From the research I've been doing it seems like the glock 19 is the most common carry gun. A local gun store has a glock 23 which fit my hand nicely so I'm sure I would like the 19. I think I want to stick with 9mm as I've heard the .40 is a little too jumpy in rapid fire situations. I'm not dead set on glock. I do, however, really like shooting my 21c. If I bought something today it would be a gen 4 glock 19 so I could change out the backstraps to fit my hand as I have very large hands. I will be carrying iwb when I carry. Does anyone have any other recommendations for a great concealed carry gun for large hands but can still conceal without printing? Thanks in advance!
