I recently started using 9mm cartridges loaded with 147 grain flat nose bullets, and a new to me issue has surfaced. It is very difficult to manually unload fully loaded 10 round magazines. Other than that there have not been any notable issues. Loading the magazines is not an issue, but manually unloading them if I don't use them in a 1911 is. The 1911 I have been using seems to have no issues feeding from magazines loaded with these cartridges. I've fired approximately 500 rounds or so and this 1911 seems to function properly with these cartridges, but I have a nagging doubt the issues I am having unloading fully loaded magazines might be an indication of potential issues down the road ?
This issue first surfaced after a practice session which ended with one fully loaded magazine that subsequently was very hard to unload. I subsequently replicated the issue with several other magazines which had otherwise worked properly when actually shooting. I never ended any of my other range visits with fully loaded magazines so this issue never came up before.
I have had no issues unloading magazines using cartridges loaded with 115 and 124 grain round nosed bullets. In the big scheme of things I can live with this issue but I am curious if this a common issue ?
Thanks in advance for any comments.
