Modular pistols are a great idea...right up until the guy running the numbers at the company realizes that this means fewer guns sold with a bigger profit margin. The other factor is that the stats guy would also say, "But modularity cuts into our market share of complete guns sold, which won't please the shareholders."

In short, it's a great idea for the military and the civilian customer, but not so good for the bottom line.
