Thank you all for the responses. Now I know why I can get 1000 rounds of 45 GAP at a pretty decent price. 45 ACP pricing like everything else, has gone through the roof and is very hard to get. I appreciate all of your feedback.
It has been impossible to get ammo. Today I could see I could get 1,000 rounds of 45 GAP. I have only ever shot .45 ACP in my 1911 RO Operator. Can 45 GAP be used in the 1911 Range Officer 1911? Thanks in advance!
