There are so many things in this industry that are well made, but all have their good and bad points. Some things are all about preference and not really better than the other. For instance, there is a certain point that a discussion about 9mm firearms being better than one another is and dumb conversation because as long as the gun is reliable for the first 5 rounds, in the real world the hits are all that counts and most shootings for even law enforcement are in the single digits. The Sig 228 is a good firearm but will need more lubrication to run properly than a Glock. If you are going on long deployment the Glock is an obvious lower maintenance firearm.
One thing we do see though is military personal mostly Special Ops that stop in our shop all buy the Safariland holsters. I personally have no problem with the drop rig Blackhawk holsters but the Safariland holsters are the ones that the pros use and that is something to pay attention to. I’ve always liked my Beretta 92 pistols and even though they are still being used in the military as a primary sidearm the guys that have the option to carry something else, do.
