OK, here is the deal, by day I'm a Glock Driver, only by department choice. I really like the M40 series and am forced into buying one. Some background on why, I also teach firearms at a Police Academy, and my department states that I can not use department issued items for secondary jobs, not a big deal. So, therefore, I am going to get a M40 for that and off-duty. Now, here are my questions for you guys. 1. Is there any inherent problems with the M40? 2. Since the initial offering, is there a new generation of the handgun? 3. What companies make off-duty concealed carry holsters that YOU WOULD TRUST YOUR LIFE WITH? 4. Is there an upgrade to the factory non-night sights? Thanks for your time, and I really like this site....OH YEAH WHERES MY AUG A3???????????????
