I just bought a new Springfield XDs .45 ACP. I love the gun and it's features; however, I've been having problems with jamming when I use 45 hollow point cartridges. The gun tends to jam when I rack it with the .45 hollow point cartridge, no problems with regular .45 using the standard 5 magazine. I've also had similar problems with jamming when using a factory bought extended cartridge (7), using regular .45 ammunition. Someone told me that the jamming problem may tend to occur, when using certain "brands" of .45 hollow points. Also, it was mentioned that there tends to be an increased chance of jamming with extended magazines. This person recommended that I pose these questions to NWfirearms.com to see if anyone else has had the same problems, and if they have had any experience with specific brands of .45 hollow point ammunition that tend not to jam this beautiful weapon. Can anyone help me? Thanks.
