OK. Why.I will ad this as someone that has seen a lot of training issues with agencies. Mechanically it shouldn't damage anything That said just because you can do something doesn't mean you should. You shouldn't run around without a 1911 thumb safety engaged. Even if you have one with a series 80 firing oin block
Yes some designs have a hammer with only a grip safetyy option (D&W M&P Shield EZ come to mind) they were designed for that and they have a hinged trigger.
So it really isn't a good idea. In a real defensive encounter the minuscule time youd safe isn't going to make or break you in a fight. Its not a speed draw like the movies.
At the end of the day one can do whatever they want just make sure your career and check book can handle.
Good luck
seriously Why.
your logic is not clear here.
