OK, so I've decided to trade in my BRICK...also known as my S&W Sigma SW9VE. I may have to 'save my pennies' for my replacement pistol, but first, it would help if I settled on a caliber....40 S&W or .45 GAP? I haven't been to my gun shop yet, but (I hope) I've narrowed my 'candidate pistols' down to these: Springfield XD SC .40: Overall Length: 6.25 inches; Weight: 26.5 oz.; Trigger Pull: 5.5 - 7.7 lbs.*** Glock 23: Overall Length: 6.85 inches; Weight: 21.16 oz.; Trigger Pull: 5.5 lbs. ? *** Glock 27: Overall Length: 6.29 inches; Overall Weight: 19.7/21.87; Trigger Pull: 5.5 lbs. ? *** Glock 30: Overall Length: 6.77": Weight: ; 23.99 oz; Trigger Pull: 5.5 lbs. *** Glock 38 .45 GAP; Overall Length: 6.85"; Weight: 24.16 oz.; Trigger Pull: 5.5 lbs. *** Glock 39 .45 GAP; Overall Length: ; 6.30"; Weight:19.33 oz. ; Trigger Pull: 5.5 lbs. I have no special affection for Glocks; they just seem to be the 'standard' against which all other pistols are measured. So, first, as someone coming from a 9mm pistol, which of the two calibers mentioned above would have less felt recoil, choosing from one of those 6 pistols? I understand that heavier guns absorb recoil better, but my pistol will also be my EDC. So, which of those six is the best 'balance' of size/weight on one hand, and least 'muzzle flip'/most controllability? If it helps, I'm 5' 7" tall and weigh about 165 pounds. Many thanks for your input.
