Switched my USP .45 from a v1 to a v3. Fairly easy to do, took some messing around. But works great!

Very easy to install the detent plate, the control lever HKN215858 is not required for functionality. Except that it lacks the 'S' and 'F' V3 lever is identical to V1

"Worthwhile Conversion"

The installation took a little thinking about as no instructions are included but if you are at all mechanically inclined you can figure it out. A good option if the piece is to be carried as you don't have to worry about the safety accidentally getting engaged. Lets face it, cocked and locked is for 1911's.

I was looking for this piece for a long time. I even talked to HK and they did not have it in stock. Suddenly, I noticed it on and grabbed one. I own two HK45Cs, and converted one of them to V3, using the Ambidextrous Control Lever Kit which I also purchased from Great conversion. Thank you Adam.

Easy install. Search for the tutorial on HKPRO. Wanted to eliminate the SAFE position and this was cheap. You don't need to be a pistol smith to do it, just not a hack. HK Parts shipped it out fast.

Simple part and easy to do it yourself. There is a youtube video and it is a 15 second change.

"DA/SA no safety"

I have converted all of my USP series pistols to V3 to fit my preference. Super easy install.

"Loose the safety!!!"

Overall Product Rating:

I've always been comfortable with DA/SA pistols and recently while practicing malfunction drills I accidentally flip the safety on. I decided to omit the safety by switching all my HKs to Variant 3 which is decock only, left side. The parts were a breeze to install and work perfectly.
