My SK-100LW has the slide lock, I still have nightmares from that microscopic spring it had. BTW...the spring from a watch band works great! The frame finish on mine looks like the matte finish on Stainless AMT gun frames.
Of course your SK-100 has a slide lock. All SK-100 had slide locks. Only the previous desing ceries the Lever Name series had versions with and without slide locks.
The spring properly installed will not get away. One end of the spring is enlarged to a press fit in the lever hole. Tough to install but stays put. I suspect some assemblers took the easy way out and installed it backwards. Most shop employees at High Standard were paid on a piece work basis. Taking the time to properly install the spring could hurt their paycheck and saying time cold help their paycheck. No matter how installed it would pass the function testing.
Mine has a slide lock on the left and right side of the frame, are they both locks, or what. Will the barrel that I find work with both or just one? Sorry about the stupid questions, but it's the only way to find out is to ask. THANK YOU
High Standard slide locks, when present, were all on the right side of fo the frame. The lever on the left side is the Safety.
The slide lock in not an issue for the SK-100 variations - all SK-100s had the slide lock. All SK-100 barrels will fit all SK-100 frames - steel, aluminum, or nickel plated aluminum variations.
