I have always had 45 acp , but lately I've been looking at the 40 s&w . Just wondering what the thought was on the pros and cons. Ballisticly ? It would be for both every day concealed carry and used for 3 gun matches . Any thoughts ? thanks

.40 on the 1911 format is just not natural!

I would guess that the "snappier" recoil from .40 would be hard on the 1911 frame. What is the round capacity on a .40 1911?

I would agree. The 1911 is MADE for the 45, but there are a lot of other calibers being run on the 1911 design. The 40 has about 3 more rounds in a single stack configuration. Like I said. I am just looking for now. thanks

It only makes sense in a 1911 if you use a double stack like a Para Ordnance or an STI. A friend has an STI Trojan single stack in 40. It's nice but the mags are 8 shot. Why use it instead of 45 for any issue other than ammo cost. Now my Para P16 Limited held 16 rounds of 40. That made sense.

By the way, is the recoil "snappier" with the 40 ? I have not yet shot one, but would assume that it would be a litttle milder. ?????

depending on what grain you are using, the .40 has a much higher velocity than the 45. Has a much more noticeable kick to it.

.40
* 8.7 g (135 Gr) Full Metal Jacket: 400 m/s (1310 ft/s)
* 11.6 g (180 Gr) Full Metal Jacket: 290 m/s (950 ft/s)


.45
* 14.7 g (230 gr) Full Metal Jacket: 260 m/s (860 ft/s)
* 11.9 g (185 gr) CCI/Speer Gold Dot JHP (from 5in (127 mm) barrel): 317 m/s (1041 ft/s)
* 14.7 g (230 gr) Federal Hi-Shok JHP (from 5 in (127 mm) barrel): 260 m/s (860 ft/s)

+ P loads

* 11.9 g (185 gr) JHP: 350 m/s (1150 ft/s)
* 14.7 g (230 gr) JHP: 290 m/s (950 ft/s)

Your .40 S&W will wear out much quicker than a comparable .45 ACP or 9mm Para because of the additional energy this round produces, especially at the beginning of the curve. I'm told by experts that a properly timed pistol can help cure this tendency. Problem is, most makers of .40s don't understand this, i.e. Glock. Therefore you get rounding on the locking surfaces to start with (this can be dangerous), and a worn out pistol at about 20K+. This is why some PDs in my area are starting to backslide from the Glock lovers of America club.

Yes, it is.
