Before I started reloading, I bought & shot reloads from gunshows by the thousands for both 9mm and 45acp.
Quality and price was excellent.
Some people, for whatever reason (since I've never seen them post data justifying their position), feel better buying/shooting dirt cheap "new" ammo produced by underpaid workers in third world countries. I don't have a problem with reloads.
Unless your .45 has been "throated" by some kitchen table gunsmith, you'll find that it is very tollerant of a wide range of loadings. Back when people used Bluedot powder, you'd hear stories of case blowouts/gun blowups from double-charging. But with bulkier powders it is very difficult to "blowup" a 45.
If you ever get a round that doesn't cycle the slide, stop shooting and investigate to make sure you don't have a bullet lodged in the barrel. Firing a second round won't blowup a modern high-quality 45 but it will destroy the barrel and possibly damage the slide.
The biggest problem with reloads is that perhaps 1 out of 5K will have problems with the primer not seated/backwards/too high.
Have a great day!
