In defense of the "training issue" with regards to the trigger pull. as a 20 year police trainer, I believe that three significant issues arose with regards to ligh crisp trigger pulls on self defense autos:
1) The amount of non-shooting cops has risen dramatically. We can't find enough shooter/ex military types that have shot guns on a regular basis, nor do they do so off duty... to put a nice 1911 in their hands, they have no concept...they NEED a "cap gun" trigger pull. Taxpayers will not shell out at union wages, to refine the training needed for that 1911.
2) Shade tree armourers killed the 1911 for police work..sorry they did. When cops were constantly "dicking around" with issue duty guns it was a trainer's and chief's nighmare. Having guns that were not going "pow" or running away full auto at the range, and on the street, was not all that rare. Have an officer's gun go to the crime lab, only to find out it had a four ounce trigger pull, , and all of the safeties had been disabled, THAT was hard to explain...the insurance carriers, the municipal attorneys, and chiefs wanted that stopped. Here comes the idiot proof gun...the Glock, sorry, I love them!
3) Product inovations since the 1980's along with the civil suit arena, placed OC Pepper spray, a metal expandable night stick, an extra pair of metal handcuffs, latex gloves for the offcer's protection, as well as a Taser on the officer's belt. Not to mention mandatory bullet proof vests. Weight is at a premium people, we lug 30 pounds of gear around...all metal pistols are too heavy...
The handgun industry counts on law enforcement and military for a lion's share of their business...it keeps their unit cost down... sportsman get those designs as an afterthought...that is why a Wilson Combat or a nice Kimber is so special...if you need one, go get one...and cherish it. Good shooting to you!:D
