I seem to remember that the all Copper (barnes) bullets Taurus has did well out of short barrels

I will try to find the data

Note--The RD was calculated by averaging the smallest and largest diameter of each recovered projectile (ex. .47 x .87 = .67). Averages for 5 shots noted below:
9 mm Black Hills/Barnes 105 gr copper JHP
Bare: VEL = 1426 f/s, PEN = 12.9” RD = 0.62”, RW = 104.4 gr
Denim: VEL = 1417 f/s, PEN = 12.7”, RD = 0.60”, RW = 104.7 gr
Auto Glass: VEL = 1444 f/s, PEN = 13.6”, RD = 0.41”, RW = 88.6 gr

.45 ACP Taurus/Barnes 185 gr copper JHP
Bare: VEL = 921 f/s, PEN = 11.7”, RD = 0.67”, RW = 184.4 gr
Denim: VEL = 922 f/s, PEN = 11.0”, RD = 0.67”, RW = 185.8 gr
Auto Glass: VEL = 924 f/s, PEN = 13.6”, RD = 0.48”, RW = 184.6 gr

While the .45 ACP copper JHP is slightly deficient in penetration, I would not hesitate to use this load when a lower penetration projectile is desired--it is more versatile in different potential engagement scenarios and far superior compared to Triton Quickshok, Aguila IQ, Magsafe, Glaser, etc...

Basically, any JHP cannot be expected to expand reliabily with less than 800 muzzle velocity, IMHO. I carry Hornady 200gr. in my Kimber Ultra Carry. Velocity is a little over 900, good expansion, good bullet weight, low flash and accurate.

Something to think about:

The heavier the bullet, the longer it stays in the bore and the more pressure it generates.

I have heard (no experience on my own) that the 3" 1911's are almost lacking in enough barrel to get sufficient energy to rack the slide.

If I noticed that 165's or 180's were leaving me out of battery or not fully running the slide, I would increase bullet weight to get more pressure into the spring.

Take my 2 cents and get some change from it.

I think you make a good point, azredhawk. I haven't had the problem...165gr works fine in my gun. That's why I compromised on 200gr, enough velocity to mushroom properly with enough weight.

I'd feel better with 230. Most .45 ACP ammo is designed for 5" or at least 4" barrels. 3" will sap a lot of velocity off the round and it isn't going all that fast to begin with. If I can't have fast bullets I figure I might as well have heavy ones. Of course 230grn is all I'd use in any .45 anyway. If I wanted light and fast, I'd use my 9mm.
