Would not fit a genuine, euro-imported H&K SP5K.

Adapters from B&T and CNC Warrior line up just fine, but the holes on this adapter were completely misaligned (literally half a pin-width off).

Contacted JMac and they said some fitment is required, i.e. break out a drill.

Requested a return as the part was clearly defective given the product description.

They refused the full refund and attempted to enforced the 20% restocking fee. But I disputed the charge and won.

(Stay away from this company or at least buy through a reseller like Optics Planet to avoid the inevitable restocking fee.)

FYI, they don't even list this part on their site anymore. It's that bad.

Mine was way too stiff. Like another reviewer, I had to use a table and my body weight to open it back up.

JMac is fully aware of the issue. But instead of correcting it, they uploaded a Rob Solomon video on their YouTube channel entitled "How to Fold your Folding Mech!" In it, they insinuate it's a lack of strength and/or technique on your part. But the comments are clear:

"...mine felt almost stuck and definitely had a frustrating break in period."

"Im a built guy and this on a vector is impossible..."

"Seriously why is mine so ridiculously tough?"

"Still doesn’t work. Two of us trying..."

"Sad, Great product but terrible customer service."

And even though this folding mechanism has been out for years, it has no reviews on their site. Whereas other products on their site only have perfect five-star reviews. Because, as I know from personal experience, they moderate and remove anything negative. It's why they enforce a 20% restocking fee for sales from their main site. People return a lot of their stuff.
