I will add to what I said earlier;
The VP9 is a good gun. If my VP9sk was a range toy I would keep it but I purchased it to carry. It is not my primary carry (I probably only carry it maybe 15-20% of the time) but I do occasionally carry it in plain clothes. My job often requires me to go into people's homes and places of work to make an arrest. My job often requires me to carry a firearm on a commercial flight. My point is, these are situations where I am carrying a firearm in confined spaces. If you often find yourself in confined spaces, that is a significantly increased chance of bumping into things, no matter how tactically aware you think you are. That is MY issue and why I made my decision.
For range use or the average civilian carrying concealed, this isn't as much of an issue. But for anyone carrying a firearm openly or someone who regularly is in a situation where the potential to use a firearm is there, particularly in a confined space, this issue is a serious concern.
I know it is difficult, particularly when there is money invested into a firearm (and holsters) that you really like. Again, everyone has to make their own decision, but to pretend that this is a non-issue is being disingenuous.
