I was in my local gun shop yesterday viewing all the eye candy....when the topic turned to a Colt series 80....he told me how it's a really great deal because of all of the choices of calibers I could use by just swapping out barrels and mags.... Is it really that simple?????
Even if you swap barrel and magazines, you still have to contend with:
feed ramp in the frame (cartridge specific in 1911s)
Notable exceptions: I can shoot .40 reliably out of my 10mm Delta Elite IF I load it long (taking it from 1.180 to 1.250) with no other changes. It simply headspaces on the extractor, not the case mouth.
I can shoot .40 and also 10mm in my SVI with only a barrel change. Both barrels were fitted to the gun.
The best gun for multi-caliber use would be a gun chambered in any of the below, since switching to any other caliber on the list should just be a barrel swap
Maybe that's what he meant.....and not .45
the series 80 is strictly 45. unless it's a mexican clone or something...
if you're interested, look up 80 series conversion kits. they're mostly found in 22LR though.
he might've been talking about a conversion kit, but those apply to pretty much any popular pistol.
they usually consist of a magazine, barrel and complete slide assembly.
if he was serious about what he said in your first post, he's gun-illiterate and is trying to feed you a hockey puck to get a sale.
