military/LE orders vs general public....
That's a common misunderstanding that many private citizens don't realize.
Major arms makers(SIG Sauer, Ruger, S&W, Glock, HK, Beretta, Colt, etc) will produce or meet orders for the military and/or LE contracts FIRST.
The fact that you may want one stainless steel handgun or one certain type of sidearm isn't going to get a large factory or company in a serious tear to manufacture it just for you.
These firms like any other productive US business want to make $$$. A signed military contract for 50,000 sidearms & spare parts or a large PD/state LE agency that wants 8,000 new weapons is going to be handled first.
It's like the funny line I read in a gun forum a long time ago; A member wrote, "Who hates the general public more? HK-USA or Federal?"
Think about that when looking for a new handgun or rifle. FWIW; 3 of the handguns I purchased have been rare LE surplus or limited ed type guns.
You'll be very lucky to find a good value with some models or brands.
