What kind of 6" barrel? My Barsto 5" is just as fast as my trophy match 6" longslide. A good barrel can make world of differents! My longslide kicks less but accuracy goes to the Barsto

Aren't typical velocities from a 1911 are around 800 feet per second?

Quoted: Aren't typical velocities from a 1911 are around 800 feet per second? As I understand it, 800-900/fps seems to be the norm. PMC seems to be the faster of the cheap stuff, IIRC. |

Pistol calibers generally create their velocity more from chamber pressure than from barrel length, I've been told. You won't see very much increase in velocity going from a 5 inch barrel to a 6 inch barrel. Even with a 16 inch barrel and "hot" loads that I wouldn't dare put in my pistols, my .45acp AR15 upper never chrony'd at more than 1300 fps with a 230 grain bullet. That's screamin' for a .45acp cartridge.

My understanding is that pistol calibers attains their max velocities in about 10-11" barrels, anything longer won't increase and in some instances decrease. |

I shoot a 200 gr. bullet out of my 1911's and they are pushing 1000 fps. but we are talking less weight. Thats your best option for a faster round. And we are still talking 200 grains, something you still don't want to get hit by, unlike the 9mm.

That's interesting, didn't know that. Makes the Mech Tech carbine adaptor for Glocks and 1911's less appealling. I assumed their 16" barrels allowed .45 acp to go supersonic. |
