Good read TooSixy. I found this part interesting:
LMAO"One of the most desirable features on the HK45CT is its very good accuracy, which in large part is due to a high-temperature rubber O-ring that fits into a groove in the barrel about 0.33 inches from the muzzle."
Wow. I'm glad my $1100 HK45C has that $5.00 (2 cent) o-ring included or it's accuracy, "in large part" would be next to nothing.
Yep. It's infrequently referred to as a "cocking ledge". Many pistols with a substantial rear sight have a "cocking ledge". The shooter pushes the pistol against a rigid or fixed edge (table, door, square post, etc.) When the slide reaches the back limit of its cycle the shooter releases from the fixed object chambering a round.Correct me if I'm wrong but the ledge is this"
