This page will be an ongoing list of commercial and political concerns for all shooters and collectors. Bad politicians and bad business will, dare I say, grace this page, as well as products and safety issues critical to collectors and shooters alike.
BEWARE, THERE ARE MANY FAKE J.P. LOWER STAMPED ARMS AND KNIVES IN THE COLLECTOR FIELD, ESPECIALLY COLT S AND WINCHESTERS. IF YOU ARE CONCERNED ABOUT A STAMP, SEND ME A PHOTO AND I'LL HELP YOU SORT THE GOOD FROM THE BAD. MANY PERSONS HAVE HAD HIS STAMP COPIED IN ORDER TO INCREASE THE VALUE OF AN OTHERWISE COMMON GUN, USUALLY ONE THAT CANNOT BE FACTORY LETTERED.
There have been many examples of Colt SA's of all generations blowing up, where as the cylinder splits in two and the top strap blows out to places unknown. Many articles have been written and theories presented, but the visable facts strongly suggest that the culprits are light trigger/bolt springs and improperly fitted or shaped bolt heads. If your cylinder "throws by" and is misalinged with the bore, and you have a hard keith type bullet, or any bullet for that matter, it has no where to go when jammed into that barrel throat. The hammer will still drop on a misalinged primer, and will set it off even if it hits the very edge in most cases. The bullet will hit the rear face of the barrel, and even if hesitating for a fraction of a second, allow pressure to build behind it that could blow the whole deal. BEWARE OF LIGHT SPRINGS AND THROW BY!!!
The thing to remember about light springs and altered parts is that for safety reasons, gun factories manufatured springs that provided positive lockup of the cylinder. In spite of the obvious savings that could have been made by using piano wire springs, they chose to keep the flat, heavy style to unsure positve lockup.
Concerning light springs and fast actions, there is no big secret to making an action smooth, and although a moderate amount of work is required, in general, the going market rate has been very inflated for two or three hours of work at various shops. It pays to shop around!
