Crispycritters, I had a bunch of SMPLs, bought from several places. The quality of the switches were differing (smoother - stickier/ stronger spring - weaker spring etc.) I also used these switches in several other mods. But there was only one similar to what you've just described above & quasi useless.I think you just weren't lucky. I'd guess they just didn't leave enough length on the threaded end. A half mm makes a huge difference.

No there was plenty of threading but I think I was just plain unlucky. I've had a few of them (all with spring switch) and some were ok - and probably decent enough compared to what was available when it was new, but that was years ago.
This thread made me dig out my old SMPL - and it's fine with a VTC5A and a 0.25 ohm single coil, but my 18650 AV Comp Lyfe mods totally outperform it.

The only thing irritating about it is it is small light and pocket friendly, until I put it in my pocket and set fire to my balls.
