Just a little extra food for thought, in general the shorter the barrel the louder the gun will be and, more recoil you will feel. There are other factors to consider such as weight when it comes to perceived recoil. As for a 1911 barrel length, from my personal experience I would choose a 5" over a 4" or, less any day of the week but, keep in mind that my uses for a 1911 would be strictly range and/or home defense so, if you’re looking at one for carry your mileage will vary.
A snub nosed .357 loses energy, quite a bit, but I trust one in .357. The one that doesn’t make sense is .38spc in a snubby. That’s where you see 12-14 inch gel penetration and the bullet not expanding with most ammo brands.
Howdy, I have found that most guns with double stack are usually just fatter not necessarily longer. Bro Edward
I prefer a shorter barrel because I carry OWB and the more barrel length it has the more it tends to stick out below my shirt and jacket. I know most people prefer IWB but I’ve yet to come to terms with that level of butt pain taking on and off a holster combined with having to buy jeans a size too big. I’m fat enough for God sake, do we really have to rub it in. As far as the difference in accuracy with a one inch difference in sight radius I personally couldn’t see it being that big but I’m sure someone’s done some kind of study.
