I have a SA pistol that is chambered in 45 LC. I purchased a conversion cylinder a few years ago that allows me to fire 45 ACP rounds through my gun that works well, is accurate and saves me a bit of money since 45 ACP rounds can be found for a LOT less than 45 colt ammo. I now have an opportunity to acquire almost 1,000 rounds of 45 GAP ammunition for next to nothing from a gun dealer I know who's retiring and selling off most of his stock. The price is outstanding yet I hate spending my hard earned money on the ammunition, regardless of the cost, if I can't use it and the dealer doesn't know if it will work or not in my gun.
My question is... does anyone know if 45 GAP ammo will fit/fire safely in a revolver chamber designed for the 45 ACP? The two round's ballistics are similar though the ACP round is slightly longer than the GAP round. I know the two aren't compatible in pistols, but many revolver cylinders will work normally/safely with more than one caliber round, 44 MAG/44 SPL and 357 MAG/38 SPL being commonly seen examples. Has anyone read if it will work or tried this themselves?
