Reinz,
I certainly respect the opinions of others on here and the fact that there are concerns about exposed trigger carry. I used to have the same concerns about carrying a cocked and locked 1911. I learned long ago at Ft Benning and then at Ft Bragg, that my safety is my finger. However, I do not recommend exposed trigger carry to anyone who is not 100% comfortable, and 100% confident in a stressful situation. That being said. I only carry exposed trigger carry on those firearms that require a calculated effort to pull the trigger. IMO, the R9's require such effort that an accidental snag on the trigger would not cause an inadvertent discharge of the weapon, but again, I don't recommend this method for anyone not comfortable, confident, properly trained, etc...only the individual can decide that. For me, I'm good with it and even carry a G27 with a light trigger this way occasionally. I defer to the many experts on this forum as to their opinion of an out of the box trigger pull on a Pup. Listen to everyone's opinion, then form your own, because in the end, it is the individual who has to answer for their decisions. Hope this helps. No matter what, exercise your 2nd Amendment rights and arm up and carry proudly.
