Well I can't tell you anything about Sig or Springfield because I've never shot them. I do carry a GLOCK 35 .40 cal. I love shooting it and very easy to clean/maintain. My friend owns a G22 gen 4 and he has told me it is a great firearm. The MAIN thing is to hopefully try each one out and see which one is most COMFORTABLE to YOU. We can only give OPINIONS to which one to choose, but the final decision is yours. Everybody has their own favorite handgun/manufacturer that they like, so you will get alot of different opinions even ones you did not list.
