Hence why go to the expense of more engineers, r and d work, and machine costs to make a product that your main buyer will not purchase, and may stop buying from you based on that pocket gun you just released to a very small consumer demand last month?
I agree. In order for the big manufacturers to take a major caliber pistol and shrink if from 6.5" down to 5.5", it would take a major re-design. So far, all these manufacturers (Glock, Springfield, S&W, H&K, etc.) have been willing to do is take a full-sized gun and chop off the barrel and the grip in several increments. Some have gone to nesting recoil springs to get sub-compacts, but that doesn't take major R&D and re-design.
Just look at Kahr. In order for Kook-Jin "Justin" Moon to break the "size barrier" an entire re-design was required. As a result, several patents came out of the effort. His reward is to sell 5000+ pocket-sized guns per year. I think the big companies have noticed this and are just not interested in this small of a market, especially with many of them selling several hundred thousand guns a year.
I think that another factor that the police and military would not be as interested in pocket-sized guns is the loss of power. These guys often encounter harder targets than consumers. Penetration is key.
If you look at some of the published specs on performance, there is a significant difference between full sized guns and pocket-sized guns.
Based on hundreds of data points found in publications combined with results of my own, I have found that when you compare a full-sized Glock 17 or Beretta 92F (M9) to pocket-sized guns in the same caliber, this is how much energy you lose:
1. Rohrbaugh R9S- 113 ft-lbs
2. Kahr PM9 - 87 ft-lbs
3. Kel-Tec PF9 - 69 ft-lbs
Here are some sub-compacts:
1. Walther PPS - 67 ft-lbs
2. Glock 26 - 47 ft-lbs
3. S&W M&P-C - 54 ft-lbs
4. Springfield XD9-C - 62 ft-lbs
I truly do not believe that police and military ignore pocket guns due to "political correctness". After all, cops do buy back-up guns. However, I believe that since they have space alloted for a full-sized weapon, they want maximum power and capacity for their primary sidearm.
An opportunity that the big gun manufacturers are missing is to shrink-down (not chop off) full sized guns so that they are pocket-sized but still have the same accuracy and power as a full sized gun. But alas, breakthroughs like this are usually left to the small start-ups.......
